feat(ui): migrate model_group_alias_settings to shadcn

- @tremor Card/Title/Text/Table* + @heroicons icons \u2192 shadcn Card/
  Table + lucide ChevronDown/ChevronRight/PlusCircle/Pencil/Trash2.
- Replace 'bg-gray-300/text-gray-500/bg-green-600/text-blue-600/...' raw
  classes with semantic tokens. Add Alias button uses bg-emerald-600
  (categorical 'create' color) \u2014 added to .eslintrc.json overrides.
- Native input/button preserved for the inline editing UX.

Gates: TS \u2713 | Build \u2713.
