feat(frontend): Implement Project Detail Page with edit and archive functionality

Add complete project detail page with real-time updates via SignalR.

Changes:
- Updated project detail page with edit and archive buttons
- Created EditProjectDialog component for updating projects
- Created ArchiveProjectDialog component for archiving projects
- Integrated SignalR real-time updates (onProjectUpdated, onProjectArchived)
- Added SignalR connection status indicator
- Enhanced useProjectHub hook to support callback options
- Improved UI layout with two-column card grid
- Added toast notifications for user feedback

Features:
- View project details (name, description, status, timestamps)
- Edit project name and description
- Archive active projects
- Real-time updates when project is modified by other users
- Automatic redirect when project is archived
