Enhance webhook detection with explicit context tracking and database optimization

- Add database index on version field for optimistic locking performance
- Implement explicit webhook context tracking with symbols to avoid conflicts
- Replace fragile webhook detection logic with robust context-based approach
- Add request metadata support for enhanced debugging and audit trails
- Simplify version management in payment collection hooks
- Fix TypeScript compilation errors and improve type safety
