Add settings tooltips and search to the web UI (#387)

* Add settings tooltips and search to the web UI

Help users quickly find settings and understand how each one works.

Tooltips: a new delegated controller (static/v3/js/tooltips.js) drives an
accessible (i) info tooltip that appears on hover, keyboard focus, and tap.
A shared `help_tip` Jinja macro (partials/_macros.html) emits the trigger;
the plugin config macro and the core settings partials now surface help
text through it. Per the design, the always-visible field help paragraphs
are folded into the tooltip to declutter the forms, and the hardware/display
settings carry authored detail (default, range, recommendation).

Search: a global header search box finds settings across every settings tab
— even ones not yet opened — via a lazy client-side index built by scanning
the same field markup (static/v3/js/settings-search.js). Selecting a result
switches tabs, waits for the field to load, then scrolls to and flashes it.
A per-tab filter box hides non-matching fields on the current tab.

Plugin settings get tooltips for free by reusing each field's schema
`description`; every settings field also gets a stable `setting-<tab>-<key>`
anchor id for search navigation.

Styling uses the existing --color-* theme vars so light/dark mode both work,
and honors prefers-reduced-motion. Adds Flask render smoke tests that assert
each settings partial ships tooltips, anchors, and a filter box.

* Address Codacy static-analysis findings in settings JS

Refactor the two new modules to clear the flagged patterns without any
behavior change:

- Build the search dropdown with DOM nodes + textContent instead of
  innerHTML string concatenation, removing the XSS sinks and the manual
  escapeHtml helper it needed.
- Replace numeric index access (index[i], terms[j], opts[idx],
  currentResults[i]) with array iteration methods, NodeList.item(), and
  Array.prototype.at() to clear detect-object-injection.
- Use === via a shared termsMatch() helper, optional-catch binding, and
  drop a useless initial assignment.

Verified with ESLint (eslint:recommended + eslint-plugin-security) at zero
findings and re-ran the headless-Chromium behavior test (tooltip, per-tab
filter, global search navigation) — all green.

* Reduce complexity of revealAncestors in settings search

Extract isNodeHidden() and revealNode() helpers so revealAncestors drops
below the cyclomatic-complexity threshold. No behavior change; verified with
the headless-Chromium test.

* Resolve remaining Codacy findings in settings search

- Validate plugin ids against a strict allowlist (mirroring the server's
  _SAFE_PLUGIN_ID_RE) before they can appear in a fetch path, so the request
  URL is never built from unvalidated input (Codacy: user-controlled URL).
- Document that the fetched HTML is parsed into an inert document (scripts
  never run, never inserted into the live DOM) purely to read field text for
  the search index.
- Declare block-scoped locals with const instead of var where they were
  nested inside conditionals (Codacy: var not at function root).

No behavior change; re-verified with ESLint and the headless-Chromium test.

* Serve the settings search index from the server as JSON

Move index building off the client so there is no client-side HTML fetching
or DOM parsing (resolves Codacy's variable-fetch and DOMParser flags on the
read-only, same-origin index build).

- Add GET /v3/settings/search-index (pages_v3.py): renders the settings
  partials server-side and extracts each field's anchor id, key, label,
  tooltip, and section with a small stdlib HTMLParser, then caches the result
  keyed on the installed-plugin set. Parsing the rendered HTML keeps anchor
  ids identical to the live DOM, so the index cannot drift.
- settings-search.js: buildIndex() now does a single fetch of the literal
  endpoint + .json(); removed the per-partial fetch loop, DOMParser, scanDoc,
  CORE_TABS, and the plugin-id allowlist. Search, keyboard nav, navigation,
  and the per-tab filter are unchanged.

Net: fewer requests and no client-side HTML parsing. Verified with a new
endpoint test in test_web_settings_ui.py (12 pass) and the headless-Chromium
test (tooltip, filter, search navigate + flash all green).

* Address CodeRabbit review on settings search/tooltips

- pages_v3: include Durations tab in the search index so
  setting-durations-* fields are actually indexed
- test_web_settings_ui: assert setting-durations-clock is present in
  the search-index endpoint response
- settings-search.js: on index fetch failure, reset buildPromise
  instead of caching an empty (truthy) index so search can retry
- settings-search.js: filterScope returns null (not document) when no
  tab container matches, and the caller guards, so the per-tab filter
  can't hide fields across unrelated tabs
- settings-search.js: refresh the stale header comment to describe the
  server-side JSON index flow
- app.css: cap #settings-search-results height with overflow-y so the
  dropdown scrolls instead of overflowing small screens

* Fix stuck search dropdown; add plugin-tab nested-settings filter

Global search:
- Close the results dropdown on input blur (guarded, with a short delay)
  so it reliably dismisses when focus leaves — previously it could linger
  because the only outside-close was a document click that Alpine/HTMX
  handlers can swallow.
- Clear the query text after navigating to a result so refocusing the box
  doesn't re-open stale results.
- Also dismiss on htmx:afterSwap (tab changes / navigation).

Per-tab filter (now on plugin tabs too):
- Render the shared settings_filter box in the plugin Configuration panel.
  It auto-wires: the delegated input handler and filterScope already target
  .plugin-config-tab.
- Teach applyTabFilter to reveal matches inside collapsed nested sections
  (render_nested_section defaults them shut), hide nested-section wrappers
  with no matches, and restore the original collapsed layout when cleared
  (only re-collapsing sections the filter itself opened).
- Count a visible nested-section as content for its parent heading so the
  heading isn't hidden while a subsection below still has matches.

Adds a plugin-config render test (filter box + nested anchors + tooltips).

* Close search dropdown via capture-phase outside-click

The dropdown could stay open after clicking away because the only
outside-click close was a bubble-phase document listener. The v3 UI is
one Alpine app() component full of HTMX/Alpine/widget click handlers;
when a click lands inside an element that calls stopPropagation(), the
event never bubbles to document and the close never runs.

- Replace the bubble-phase document 'click' close with a capture-phase
  'pointerdown' listener scoped to #settings-search-wrap. Capture runs
  before any bubbling stopPropagation can swallow the event, so it always
  fires; pointerdown also covers touch on the Pi screen. Clicking a result
  stays inside the wrap, so selection is unaffected.
- Guard the debounced input handler so a delayed render can't re-open the
  box after focus has left (type-then-click-away race).

Keeps the existing blur / Escape / htmx:afterSwap closes as secondary paths.

* Fix settings search dropdown not visually closing

.hidden has no effect in this app: app.css is a hand-picked utility
subset (no Tailwind build step) and never defines .hidden { display:
none }. openResults()/closeResults() only toggled the class, so the
dropdown stayed rendered (display: block) even once closeResults()
ran - confirmed via computed style in a headless browser. Set
style.display directly, matching the fallback already used by
revealNode()/collapseNode() elsewhere in this file.
