- Created CreateStoryDialog for story creation with epic selection
- Added useProjectStories hook to fetch all stories across epics for a project
- Refactored Kanban page to show Stories only with drag-and-drop status updates
- Updated SignalR event handlers to focus on Story events only
- Changed UI text from 'New Issue' to 'New Story' and 'update issue status' to 'update story status'
- Implemented story status change via useChangeStoryStatus hook
