feat(admin): implement App Registry drawer and handlers (Slice 1) (#78)

- Added "+ Register App" button and `#appDrawer` form to `src/features/admin/apps_fragments.tsx`.
- Implemented action buttons (Edit, Delete) using HTML5 `data-*` attributes for safe JSON parsing.
- Implemented global `openCreateAppDrawer`, `openEditAppDrawer`, `closeAppDrawer`, `handleSaveApp`, and `deleteApp` handlers in `public/admin-scripts.js`.
- Fixed missing `spiffe_id` property mapping in payload.
- Added corresponding Role and Invite handlers to `public/admin-scripts.js` for completeness.
- Verified components render correctly via assertions in `src/features/admin/admin.test.ts`.
