Chuck a8c85dd015 feat(widgets): add modular widget system for schedule and common inputs (#213) ...

* feat(widgets): add modular widget system for schedule and common inputs

Add 15 new reusable widgets following the widget registry pattern:
- schedule-picker: composite widget for enable/mode/time configuration
- day-selector: checkbox group for days of the week
- time-range: paired start/end time inputs with validation
- text-input, number-input, textarea: enhanced text inputs
- toggle-switch, radio-group, select-dropdown: selection widgets
- slider, color-picker, date-picker: specialized inputs
- email-input, url-input, password-input: validated string inputs

Refactor schedule.html to use the new schedule-picker widget instead
of inline JavaScript. Add x-widget support in plugin_config.html for
all new widgets so plugins can use them via schema configuration.

Fix form submission for checkboxes by using hidden input pattern to
ensure unchecked state is properly sent via JSON-encoded forms.

* fix(widgets): improve security, validation, and form binding across widgets

- Fix XSS vulnerability: escapeHtml now escapes quotes in all widget fallbacks
- color-picker: validate presets with isValidHex(), use data attributes
- date-picker: add placeholder attribute support
- day-selector: use options.name for hidden input form binding
- password-input: implement requireUppercase/Number/Special validation
- radio-group: fix value injection using this.value instead of interpolation
- schedule-picker: preserve day values when disabling (don't clear times)
- select-dropdown: remove undocumented searchable/icons options
- text-input: apply patternMessage via setCustomValidity
- time-range: use options.name for hidden inputs
- toggle-switch: preserve configured color from data attribute
- url-input: combine browser and custom protocol validation
- plugin_config: add widget support for boolean/number types, pass name to day-selector
- schedule: handle null config gracefully, preserve explicit mode setting

* fix(widgets): validate day-selector input, consistent minLength default, escape JSON quotes

- day-selector: filter incoming selectedDays to only valid entries in DAYS array
  (prevents invalid persisted values from corrupting UI/state)
- password-input: use default minLength of 8 when not explicitly set
  (fixes inconsistency between render() and onInput() strength meter baseline)
- plugin_config.html: escape single quotes in JSON hidden input values
  (prevents broken attributes when JSON contains single quotes)

* feat(widgets): add global notification widget, consolidate duplicated code

- Create notification.js widget with toast-style notifications
- Support for success, error, warning, info types
- Auto-dismiss with configurable duration
- Stacking support with max notifications limit
- Accessible with aria-live and role="alert"
- Update base.html to load notification widget early
- Replace duplicate showNotification in raw_json.html

* fix(widgets): escape options.name in all widgets, validate day-selector format

Security fixes:
- Escape options.name attribute in all 13 widgets to prevent injection
- Affected: color-picker, date-picker, email-input, number-input,
  password-input, radio-group, select-dropdown, slider, text-input,
  textarea, toggle-switch, url-input

Defensive coding:
- day-selector: validate format option exists in DAY_LABELS before use
- Falls back to 'long' format for unsupported/invalid format values

* fix(plugins): add type="button" to control buttons, add debug logging

- Add type="button" attribute to refresh, update-all, and restart buttons
  to prevent potential form submission behavior
- Add console logging to diagnose button click issues:
  - Log when event listeners are attached (and whether buttons found)
  - Log when handler functions are called

* fix(widgets): improve security and validation across widget inputs

- color-picker.js: Add sanitizeHex() to validate hex values before HTML
  interpolation, ensuring only safe #rrggbb strings are used
- day-selector.js: Escape inputName in hidden input name attribute
- number-input.js: Sanitize and escape currentValue in input element
- password-input.js: Validate minLength as non-negative integer, clamp
  invalid values to default of 8
- slider.js: Add null check for input element before accessing value
- text-input.js: Clear custom validity before checkValidity() to avoid
  stale errors, re-check after setting pattern message
- url-input.js: Normalize allowedProtocols to array, filter to valid
  protocol strings, and escape before HTML interpolation

* fix(widgets): add defensive fallback for DAY_LABELS lookup in day-selector

Extract labelMap with fallback before loop to ensure safe access even if
format validation somehow fails.

* feat(widgets): add timezone-selector widget with IANA timezone dropdown

- Create timezone-selector.js widget with comprehensive IANA timezone list
- Group timezones by region (US & Canada, Europe, Asia, etc.)
- Show current UTC offset for each timezone
- Display live time preview for selected timezone
- Update general.html to use timezone-selector instead of text input
- Add script tag to base.html for widget loading

* fix(ui): suppress on-demand status notification on page load

Change loadOnDemandStatus(true) to loadOnDemandStatus(false) during
initPluginsPage() to prevent the "on-demand status refreshed"
notification from appearing every time a tab is opened or the page
is navigated. The notification should only appear on explicit user
refresh.

* style(ui): soften notification close button appearance

Replace blocky FontAwesome X icon with a cleaner SVG that has rounded
stroke caps. Make the button circular, slightly transparent by default,
and add smooth hover transitions for a more polished look.

* fix(widgets): multiple security and validation improvements

- color-picker.js: Ensure presets is always an array before map/filter
- number-input.js: Guard against undefined options parameter
- number-input.js: Sanitize and escape min/max/step HTML attributes
- text-input.js: Clear custom validity in onInput to unblock form submit
- timezone-selector.js: Replace legacy Europe/Belfast with Europe/London
- url-input.js: Use RFC 3986 scheme pattern for protocol validation
- general.html: Use |tojson filter to escape timezone value safely

* refactor(url-input): centralize RFC 3986 protocol validation

Extract protocol normalization into reusable normalizeProtocols()
helper function that validates against RFC 3986 scheme pattern.
Apply consistently in render, validate, and onInput to ensure
protocols like "git+ssh", "android-app" are properly handled
everywhere. Also lowercase protocol comparison in isValidUrl().

* fix(timezone-selector): use hidden input for form submission

Replace direct select name attribute with a hidden input pattern to
ensure timezone value is always properly serialized in form submissions.
The hidden input is synced on change and setValue calls. This matches
the pattern used by other widgets and ensures HTMX json-enc properly
captures the value.

* fix(general): preserve timezone dropdown value after save

Add inline script to sync the timezone select with the hidden input
value after form submission. This prevents the dropdown from visually
resetting to the old value while the save has actually succeeded.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(widgets): preserve timezone selection across form submission

Use before-request handler to capture the selected timezone value
before HTMX processes the form, then restore it in after-request.
This is more robust than reading from the hidden input which may
also be affected by form state changes.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(widgets): add HTMX protection to timezone selector

Add global HTMX event listeners in the timezone-selector widget
that preserve the selected value across any form submissions.
This is more robust than form-specific handlers as it protects
the widget regardless of how/where forms are submitted.

* debug(widgets): add logging and prevent timezone widget re-init

Add debug logging and guards to prevent the timezone widget from
being re-initialized after it's already rendered. This should help
diagnose why the dropdown is reverting after save.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* debug: add console logging to timezone HTMX protection

* debug: add onChange logging to trace timezone selection

* fix(widgets): use selectedIndex to force visual update in timezone dropdown

The browser's select.value setter sometimes doesn't trigger a visual
update when optgroup elements are present. Using selectedIndex instead
forces the browser to correctly update the visible selection.

* fix(widgets): force browser repaint on timezone dropdown restore

Adding display:none/reflow/display:'' pattern to force browser to
visually update the select element after changing selectedIndex.
Increased timeout to 50ms for reliability.

* chore(widgets): remove debug logging from timezone selector

Clean up console.log statements that were used for debugging the
timezone dropdown visual update issue.

* fix(ui): improve HTMX after-request handler in general settings

- Parse xhr.responseText with JSON.parse in try/catch instead of
  using nonstandard responseJSON property
- Check xhr.status for 2xx success range
- Show error notification for non-2xx responses
- Default to safe fallback values if JSON parsing fails

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(widgets): add input sanitization and timezone validation

- Sanitize minLength/maxLength in text-input.js to prevent attribute
  injection (coerce to integers, validate range)
- Update Europe/Kiev to Europe/Kyiv (canonical IANA identifier)
- Validate timezone currentValue against TIMEZONE_GROUPS before rendering

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(ui): correct error message fallback in HTMX after-request handler

Initialize message to empty string so error responses can use the
fallback 'Failed to save settings' when no server message is provided.
Previously, the truthy default 'Settings saved' would always be used.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(widgets): add constraint normalization and improve value validation

- text-input: normalize minLength/maxLength so maxLength >= minLength
- timezone-selector: validate setValue input against TIMEZONE_GROUPS
- timezone-selector: sync hidden input to actual selected value
- timezone-selector: preserve empty selections across HTMX requests

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(widgets): simplify HTMX restore using select.value and dispatch change event

Replace selectedIndex manipulation with direct value assignment for cleaner
placeholder handling, and dispatch change event to refresh timezone preview.
