✨ feat(auth): add error logs API and database schema

Add centralized error logging endpoint to mana-core-auth:
- Error logs database schema with app_id, error message, stack traces
- POST /error-logs endpoint for single errors
- POST /error-logs/batch endpoint for batch submissions
- Error logs service with automatic cleanup of old entries
- DTOs with validation for error log submissions
