feat: Add collaborative lists (#2146)

* feat: Add collaborative lists backend implementation

This commit implements the core backend functionality for collaborative
lists, allowing multiple users to share and interact with bookmark lists.

Database changes:
- Add listCollaborators table to track users with access to lists and
  their roles (viewer/editor)
- Add addedBy field to bookmarksInLists to track who added bookmarks
- Add relations for collaborative list functionality

Access control updates:
- Update List model to support role-based access (owner/editor/viewer)
- Add methods to check and enforce permissions for list operations
- Update Bookmark model to allow access through collaborative lists
- Modify bookmark queries to include bookmarks from collaborative lists

List collaboration features:
- Add/remove/update collaborators
- Get list of collaborators
- Get lists shared with current user
- Only manual lists can have collaborators

tRPC procedures:
- addCollaborator: Add a user as a collaborator to a list
- removeCollaborator: Remove a collaborator from a list
- updateCollaboratorRole: Change a collaborator's role
- getCollaborators: Get all collaborators for a list
- getSharedWithMe: Get all lists shared with the current user
- cloneBookmark: Clone a bookmark to the current user's collection

Implementation notes:
- Editors can add/remove bookmarks from the list (must own the bookmark)
- Viewers can only view bookmarks in the list
- Only the list owner can manage collaborators and list metadata
- Smart lists cannot have collaborators (only manual lists)
- Users cannot edit bookmarks they don't own, even in shared lists

* feat: Add collaborative lists frontend UI

This commit implements the frontend user interface for collaborative lists,
allowing users to view shared bookmarks and manage list collaborators.

New pages:
- /dashboard/shared: Shows bookmarks from lists shared with the user
  - Displays bookmarks from all collaborative lists
  - Uses SharedBookmarks component
  - Shows empty state when no lists are shared

Navigation:
- Added "Shared with you" link to sidebar with Users icon
- Positioned after "Home" in main navigation
- Available in both desktop and mobile sidebar

Collaborator management:
- ManageCollaboratorsModal component for managing list collaborators
  - Add collaborators by user ID with viewer/editor role
  - View current collaborators with their roles
  - Update collaborator roles inline
  - Remove collaborators
  - Shows empty state when no collaborators
- Integrated into ListOptions dropdown menu
- Accessible via "Manage Collaborators" menu item

Components created:
- SharedBookmarks.tsx: Server component fetching shared lists/bookmarks
- ManageCollaboratorsModal.tsx: Client component with tRPC mutations
- /dashboard/shared/page.tsx: Route for shared bookmarks page

UI features:
- Role selector for viewer/editor permissions
- Real-time collaborator list updates
- Toast notifications for success/error states
- Loading states for async operations
- Responsive design matching existing UI patterns

Implementation notes:
- Uses existing tRPC endpoints (getSharedWithMe, getCollaborators, etc.)
- Follows established modal patterns from ShareListModal
- Integrates seamlessly with existing list UI
- Currently uses user ID for adding collaborators (email lookup TBD)
