Summary

This PR adds full tags and genre support to the door configuration forms, JS-DOS doors, and manifest editors:

1. Category Picker Dropdown in DoorConfigForm:

   • Upgrades field.type === 'tags' in door-config-form.js to render an input group combining the comma-separated text input (with datalist autocomplete) and an "Add category..." dropdown selector populated from #manifestCategoriesList / standard categories.
   • Selecting a tag appends it to the input without duplication.
   • Adds fallback to manifest default tags (info.genre) if no runtime override is set in config/{type}doors.json so existing door tags are visible when editing.

2. JS-DOS & Web Door Manifest Definitions:

   • Adds genre (type tags) to JsdosDoorManifestDefinition under game_info.
   • Adds game.genre (type tags) to WebDoorManifestDefinition.
   • Adds genre to DoorRuntimeFields::getAllowedKeys('jsdos') with array parsing in merge().

3. Runtime Overrides & AI Auto-fill:

   • In routes/webdoor-routes.php, respects runtime gameConfig['genre'] overrides for JS-DOS doors if specified.
   • In routes/admin-routes.php, supplies standard_categories to /admin/jsdosdoors.
   • In door manifest AI auto-fill, maps to both prefixed and top-level fields (genre and game.genre).

4. Cache Busting:

   • Adds ?v=1.3.0 to /js/door-config-form.js script tags across door config templates to ensure browsers load the updated component.
