v1.2.10: Fix critical betting system bugs and enhance stability

Critical Fixes:
- Fixed SQLite NOT NULL constraint violation in bet creation API by properly extracting fixture_id from match data
- Resolved 500 error in bet details page route by implementing complete database data fetching and template variable population
- Fixed moment() undefined template rendering error by removing server-side JavaScript calls and using client-side time handling
- Corrected JavaScript API endpoint mismatches (POST /cancel vs DELETE /bets/{uuid}) and added missing event handlers

Bug Fixes:
- Enhanced bet creation logic to query MatchModel and extract fixture_id from first bet detail's match
- Implemented comprehensive bet details route with database session management and statistics calculation
- Fixed template compatibility issues by eliminating server-side/client-side JavaScript conflicts
- Added proper event listeners for delete bet detail buttons in bet management interface

Database & API Improvements:
- Ensured proper foreign key relationships between bets, bet_details, and matches tables
- Enhanced error handling with proper HTTP status codes and user-friendly messages
- Fixed attribute reference from column_value to float_value in MatchOutcomeModel queries
- Improved database constraint compliance and data consistency validation

Documentation Updates:
- Updated README.md with version 1.2.10 critical bug fixes and stability improvements
- Enhanced CHANGELOG.md with detailed technical fixes and implementation details
- Added comprehensive troubleshooting section to DOCUMENTATION.md with root cause analysis

The betting system is now fully functional with:
✅ Complete CRUD operations without database constraint violations
✅ Proper bet details page display with comprehensive information
✅ Fixed JavaScript API interactions and event handling
✅ Stable template rendering without server-side JavaScript conflicts
✅ Enhanced error handling and user experience

 ### Betting System Troubleshooting
 
+#### Critical Database Constraint Errors (Fixed in v1.2.10)
+
+**Symptoms**: "NOT NULL constraint failed: bets.fixture_id" error during bet creation
+**Root Cause**: Bet creation API was setting fixture_id to None without extracting it from match data
+**Solution Applied**: Enhanced bet creation logic to query MatchModel and extract fixture_id from first bet detail's match
+**Prevention**: Ensure all bet creation requests include valid match_id references with existing matches
+
+#### Bet Details Page 500 Errors (Fixed in v1.2.10)
+
+**Symptoms**: 500 internal server error when accessing specific bet details pages
+**Root Cause**: Route was not fetching bet data from database, causing template rendering failures
+**Solution Applied**: Implemented complete database data fetching with proper session management and template variable population
+**Prevention**: Always verify route implementations provide all required template variables
+
+#### Template Rendering JavaScript Errors (Fixed in v1.2.10)
+
+**Symptoms**: "'moment' is undefined" error during template rendering causing 500 errors
+**Root Cause**: Template attempted to call moment() function in server-side Jinja2 context
+**Solution Applied**: Replaced server-side moment() call with client-side JavaScript time handling
+**Prevention**: Avoid client-side JavaScript libraries in server-side template contexts
+
+#### API Endpoint Mismatches (Fixed in v1.2.10)
+
+**Symptoms**: Cancel bet functionality not working, JavaScript errors on bet management actions
+**Root Cause**: Frontend JavaScript calling wrong API endpoints and missing event handlers
+**Solution Applied**: Corrected API endpoints and added comprehensive event handling for interactive elements
+**Prevention**: Verify API endpoint consistency between frontend and backend implementations
