fix(web): address CodeRabbit review — validation, a11y, perf, and privacy fixes

Verified each finding against current code. Fixed:

- api_v3: plugin_rotation_order is now strictly validated (JSON list of
  strings, 400 with a descriptive message otherwise) and popped from the
  payload before any further handling.
- display_controller: _apply_plugin_rotation_order defensively ignores a
  non-list value (keeps the existing rotation, logs a warning) and drops
  non-string entries; new logs carry the [DisplayController] prefix.
  Unit-tested both defensive paths.
- app.py: snapshot-read handler narrowed to OSError with debug logging;
  flask-compress ImportError now emits one structured warning with the
  install remedy.
- htmx-config: the response-error logger prints form FIELD NAMES only -
  values (API keys, passwords) never reach the console.
- plugin-order-list: saved order/exclusions normalized with Array.isArray
  (a saved "null" previously crashed .forEach); each row gained
  keyboard/touch-accessible move-up/move-down buttons (HTML5 drag events
  don't fire on most mobile browsers) that reorder and syncInputs()
  immediately alongside native drag.
- app-shell: window.installedPlugins setter always takes the new list
  (same-ID metadata/enabled updates were silently dropped); tab rebuild
  stays gated on ID changes. LED dot renderer reads the frame with ONE
  getImageData call instead of one per pixel (~9,200/frame at 192x48).
- plugins_manager: togglePlugin returns its request promise resolving the
  API outcome; the install flow now shows the "installed and enabled"
  toast (with Restart Now) only after enablement succeeds, and a warning
  without a restart offer when it fails.
- a11y: hamburger aria-label flips Open/Close with drawer state; both
  Advanced-section toggle buttons declare aria-controls/aria-expanded and
  the shared toggleSection() keeps aria-expanded in sync; move buttons
  have per-plugin aria-labels.
- Rotation/Vegas order-list bootstraps cap their retries (~5s) and show a
  reload hint instead of spinning forever; Alpine app-state lookups prefer
  [x-data="app()"] with a generic fallback.

Skipped, with reasons:
- executePluginAction arg order: caller (plugin_config.html) already
  passes (actionId, index, pluginId) matching the signature exactly.
- generateFieldHtml XSS, entity-unescape blocks, dotToNested pollution,
  and "app.loadInstalledPlugins" in app-shell: all inside the legacy
  client-side config cluster whose entry points are shadowed by
  plugins_manager.js / replaced by server-rendered forms (zero live
  callers, verified) - queued for wholesale deletion in the follow-up
  rather than patching dead code.
- custom-feeds-helpers.js findings (3): file was deleted in a prior commit.
- console.error/warn override removal and afterSwap script re-execution
  removal: deliberate pre-existing workarounds every partial's inline
  init currently depends on; reworking them safely needs isolated testing
  (follow-up), and the error suppression is already double-gated
  (insertBefore AND htmx match).
- "move durations bootstrap into a bundle": inline partial-scoped init is
  the established pattern for HTMX partials in this codebase.

Validation: all 40 web tests pass; py_compile on all touched Python; all
touched templates parse; rotation-order defensive paths unit-tested.
