fix: additional code quality and performance improvements
Code quality:
- Remove empty except blocks with proper logging
- Create shared pagination utility function
- Remove duplicate UUID validation code
- Fix dead code in translation.py
Performance:
- Fix N+1 query in followup engine (use join instead of loop)
- Add eager loading for customer health scores
- Create database indexes for common query patterns:
- customers: (user_id, status), (user_id, last_contact_at)
- payment_transactions: (user_id, created_at)
- followup_logs: (user_id, customer_id)
- notifications: (user_id, is_read)
Configuration:
- Centralize magic numbers in config.py:
- Payment prices
- File upload limits
- Rate limiting settings
- Pagination defaults
- Update auth.py to use centralized rate limiting config
- Update customer/product imports to use centralized upload limits
- Update import_service.py to use centralized MAX_ROWS
