Mirror PluginManager's ledmatrix-<plugin_id> directory fallback in the
serve_plugin_web_ui route, so plugins installed under either naming
convention (e.g. 'flights' on-disk as 'ledmatrix-flights') are served
correctly. Addresses coderabbit review comment.

## Security fixes
### pages_v3.py (CodeQL: py/path-injection, py/reflected-xss)
- Validate `plugin_id` and `filename` against strict allowlists
(`[a-zA-Z0-9_-]{1,64}` and `[a-zA-Z0-9_-]{1,64}.html`) before any
path or script operations — satisfies CodeQL path-injection checks
- Error responses returned as `text/plain` with no user data in body
- HTML-meta-char escaping on PLUGIN_ID value in script tag (defence in depth)
### array-table.js (CodeQL: js/prototype-pollution)
- Guard `setNestedValue()` against `__proto__`, `prototype`, and
`constructor` keys; silently drops any write targeting those keys
### plugin-file-manager.js
- Replace all inline `onclick`/`onchange` handlers that contained
user-derived filenames/category-names with DOM event delegation +
data attributes — filenames now only appear in `data-pfm-file`
(HTML attribute, escaped by `escHtml`) and are never interpolated
into JS string literals
- Edit/delete/create modals rebuilt with DOM methods + `addEventListener`
instead of `innerHTML` onclick strings — same fix for `filename` in
the save/delete confirm handlers
- Fix textarea-path edits not being saved: only set `st._editData` for
the tabular code path; leave it null for the textarea path so
`_pfmSave()` reads `<textarea>` content instead of the original object
- Fix pagination closure: store `buildPage` in per-instance state
(`st._buildPage`); `window._pfmTablePage` dispatches to the correct
instance by fieldId — multiple instances no longer clobber each other
### time-picker.js
- Call `widget.validate(fieldId)` after `onClear()` to keep required-field
error state accurate when the field is cleared
### plugin_config.html
- Honor `x_widget` alias (underscore) alongside `x-widget` (hyphen) in
the new server-side array-table column rendering branches
- Same fix for the `has_file_manager_widget` suppression check
### widget-guide.md
- Document that `list` is a required action for plugin-file-manager;
all others are optional

## New widgets
### plugin-file-manager (reusable)
Inline file management UI driven entirely by x-widget-config in the plugin schema.
Any plugin can adopt it by declaring web_ui_actions in manifest.json and adding
x-widget: "plugin-file-manager" to their config schema.
Features:
- File card grid with enable/disable toggles, metadata (entry count, size, date)
- Drag-and-drop + click upload zone with configurable hint text
- Create file modal driven by create_fields schema config
- Delete confirmation modal
- Edit modal: auto-detects tabular data (object-of-objects) → paginated table
with inline-editable cells and "Jump to today" navigation; falls back to
JSON textarea for unstructured data
- plugin_id auto-injected from template context; no per-plugin JS needed
- Immediate saves via /api/v3/plugins/action — no Save Configuration required
### time-picker
Wraps native <input type="time">, returns HH:MM string. Generic, zero config.
### file-upload-single
Single-image upload for string fields. Shows thumbnail preview + clear button.
plugin_id auto-injected from template context.
## New route (pages_v3.py)
GET /v3/plugin-ui/<plugin_id>/web-ui/<filename>
Serves a plugin's web_ui/ HTML fragment as a standalone page, wrapping it with
a minimal HTML page that injects window.PLUGIN_ID and loads Tailwind CSS.
Enables the json-file-manager iframe fallback (Phase A) and future plugin UIs.
## plugin_config.html updates
- json-file-manager: renders plugin's web_ui/file_manager.html in an iframe
via the new /v3/plugin-ui/ route (Phase A compatibility)
- plugin-file-manager: full inline widget registration
- time-picker, file-upload-single: registered in widget elif chain
- color-picker: wired for type:array (RGB triplet) fields — renders hex picker
+ R/G/B number inputs with bidirectional sync
- Plugin Actions section: suppressed when schema has a file-manager widget
or when all actions are marked ui_hidden in manifest
- x-widget-config passed to all widgets in the init script block
## array-table.js improvements (v2.0.0)
- enum fields → <select> dropdown instead of plain text
- date-picker x-widget → <input type=date>
- time-picker x-widget → <input type=time>
- file-upload-single x-widget → path input + upload button + thumbnail
- Row edit modal (⚙) for non-displayed nested properties (layout, style objects)
with color pickers, enum selects, number inputs
- getValue() collects <select> values and nested key paths
- Inline image upload via handleArrayTableImageUpload()

If plugin_dir somehow resolves to '/' or a bare drive root, os.path.basename()
returns '', causing safe_plugin_dir to equal plugins_dir_real and the isdir()
check to pass incorrectly. Reject early with a clear error in that case.

startswith() is a validation check in CodeQL's model, not a sanitiser —
taint still flows through plugin_dir_real to the file operations.
os.path.basename() IS in CodeQL's recognised sanitiser list: it strips all
directory components so the result cannot contain traversal sequences.
Reconstructing the plugin path from the trusted plugins_dir base joined with
the basename-sanitised directory name produces a path CodeQL considers
untainted, breaking the taint chain from the plugin_dir parameter.

Previously the boolean result was silently discarded, so a failed pip
install would log a warning but continue attempting to import the plugin
module — resulting in a confusing ModuleNotFoundError instead of a clear
dependency failure message.
Now raises PluginError with plugin_id and plugin_dir if dependency
installation fails, stopping the load before the import is attempted.

Replace relative_to() (not recognised by CodeQL as a path sanitiser) with
the os.path.realpath() + startswith() pattern that CodeQL explicitly models
as sanitising py/path-injection.
- Add plugins_dir optional param to install_dependencies() and load_plugin()
- PluginManager.load_plugin() passes self.plugins_dir as the trusted anchor;
install_dependencies() validates that the resolved plugin_dir starts with
the resolved plugins_dir before any file I/O
- Replace all Path.read_bytes/read_text/write_text/exists with open() and
os.path.isfile() so the sanitised string paths flow directly to file ops
without re-introducing taint through Path object conversion

- Add explicit relative_to() containment check after path resolution so
CodeQL recognizes the plugin directory boundary (fixes 4 CodeQL alerts:
Uncontrolled data used in path expression, lines 168/172/189/205)
- Wrap requirements_file.read_bytes() in try/except OSError — on Raspberry
Pi with flaky SD card storage this can fail; returns False with a clear log
- Wrap marker_path.read_text() in try/except OSError — a corrupted marker
falls through to a clean reinstall instead of crashing
- Wrap both marker_path.write_text() calls in try/except OSError — pip
already succeeded at this point so a marker write failure should not
return False or propagate through the generic exception handler

The .dependencies_installed marker was an empty file, so adding a new
package to requirements.txt (e.g. astral in ledmatrix-weather v2.3.0)
never triggered a pip re-install on existing installs — the file existed
so the check returned early.
The marker now stores a SHA-256 hash of requirements.txt. On every plugin
load, the loader compares the current hash to the stored one; a mismatch
(or missing marker) triggers pip install and writes the new hash.
store_manager._install_dependencies() also writes the hash marker after a
store install/update so the loader skips a redundant pip run on next boot.
