feat(api_key): implement comprehensive API key management system

- Add complete API key CRUD operations with validation
- Implement unified AuthChain middleware for consistent authentication
- Add API key management endpoints with proper error handling
- Enhance database schema for API key storage and relationships
- Add comprehensive validation for API key creation and updates
- Implement multi-language localization support for API key management
- Remove unused authentication methods and streamline middleware
- Add proper field validation and required field enforcement

This implementation provides a robust foundation for API key-based
authentication across the Peekaping monitoring platform.
