Integrate NavigationMenuItem with feature flag support (#17268)

## Implement Navigation Menu Items Frontend

Implements the frontend for navigation menu items, the new system
replacing favorites.

### Changes
- Added GraphQL fragments and queries for navigation menu items
- Added hooks for managing navigation menu items (create, update,
delete, sorting, filtering)
- Updated components to use navigation menu items instead of favorites
- Added test coverage for utility functions

### Migration Note
The favorites and navigation menu item modules currently exist in
parallel. The favorites code will be removed once all data has been
migrated to navigation menu items.

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Replaces Favorites with feature-flagged `NavigationMenuItem` across
frontend and backend, while keeping Favorites as fallback until
migration completes.
> 
> - UI: new `navigation-menu-item` components (folders, orphan items,
drag provider/droppable, icons, skeleton), dispatcher components to
switch from Favorites, and updated “Add to favorites” action to create
`NavigationMenuItem` when `IS_NAVIGATION_MENU_ITEM_ENABLED`
> - DnD: shared `validateAndExtractFolderId` and droppable id utils
moved to `ui/layout/draggable-list`; favorites DnD updated to use shared
utils
> - GraphQL (client): add fragments, queries, mutations, hooks
(create/update/delete/find), and generated types; added
`RecordIdentifier` and `targetRecordIdentifier` on `NavigationMenuItem`
> - Prefetch: new prefetch state/effect for navigation menu items; skip
favorites prefetch when flag enabled
> - Backend: add DTOs (`NavigationMenuItem`, `RecordIdentifier`),
resolver `targetRecordIdentifier` field, service logic to fetch record
identifiers with permission-aware access and image signing,
`getRecordImageIdentifier` util, entity relation to `view`, and
migration adding FK on `viewId`
> - Feature flags & seeding: add `IS_NAVIGATION_MENU_ITEM_ENABLED` to
enums, dev seeder enables it; standard app seeds workspace navigation
menu items instead of favorites when flag on
> - Tests: add unit tests for sorting/labels/folder id and related utils
