fix(ui): remove per-node active-filters chip from loras widgets

The indicator chip added for /activefilters discoverability was broken by
design of its import path: AutocompleteTextWidget.vue imported
web/comfyui/settings.js into the vue-widgets bundle, and settings.js's
"../../scripts/app.js" import resolved at build time to the repo-root test
shim (scripts/app.js, an in-memory settings store). The chip therefore read
and wrote an orphaned in-memory Map: clicking it flipped only its own
visual state and never touched the real ComfyUI setting that
autocomplete.js consults (use_active_filters query param).

Beyond the defect, a persistent per-node control for a global persisted
setting misleads users and needs cross-instance sync machinery, which the
footer hint, slash commands, right-click menu entry and settings dialog
already cover.

- AutocompleteTextWidget.vue: remove the chip button, its state/handlers,
  the settings.js import (the shim-inlining pathway) and all chip styles
- AutocompleteTextWidget.test.ts: drop the chip indicator describe block
  and the settings.js module mock; beforeEach import no longer needed
- settings.js: drop the lora-manager:setting-toggled window broadcast and
  its export — the chip was its only consumer, so every
  setLoraManagerSettingValue write no longer dispatches a dead event
- autocomplete.activeFilters.test.js: drop the broadcast assertion test
- loraLoader.activeFiltersMenu.test.js: drop SETTING_TOGGLED_EVENT_NAME
  from the settings.js mock

Discoverability of /activefilters // /noactivefilters is unchanged:
command-list footer, first-run hint, node context menu, settings dialog.
