feat(ui): improve /activefilters discoverability on loras nodes

Mirror the /noautocomplete discoverability pattern for the loras\nactive-filters search toggle:\n\n- autocomplete.js: extend the slash-command-list footer and the\n  one-time first-run hint to loras nodes, advertising\n  /activefilters and /noactivefilters\n- lora_loader.js: add an 'Active Filters Search: ON/OFF' entry to the\n  right-click menu of all loras-autocomplete node classes\n- settings.js: broadcast a 'lora-manager:setting-toggled' window event\n  on every setLoraManagerSettingValue write\n- AutocompleteTextWidget.vue: add a persistent filter indicator chip\n  (loras mode only) that reflects and toggles the setting and stays in\n  sync via the setting-toggled event\n- tests: footer/hint/event coverage, context-menu tests for all four\n  node classes, widget indicator tests; rebuild vue-widgets bundle
