feat: Complete standardized error handling across all models

Browse Source 
- Create comprehensive error infrastructure in backend/utils/modelErrors.js
- Implement consistent error handling patterns across all 11 models
- Add proper try-catch blocks, validation, and error logging
- Standardize error messages and error types
- Maintain 100% test compatibility (221/221 tests passing)
- Update UserBadge.js with flexible validation for different use cases
- Add comprehensive field validation to PointTransaction.js
- Improve constructor validation in Street.js and Task.js
- Enhance error handling in Badge.js with backward compatibility

Models updated:
- User.js, Post.js, Report.js (Phase 1)
- Event.js, Reward.js, Comment.js (Phase 2)
- Street.js, Task.js, Badge.js, PointTransaction.js, UserBadge.js (Phase 3)
