Task: Refactor Controller Layer for API and Worker Management

Description

Refactor the existing controller layer to provide clean interfaces for API endpoints and background workers, ensuring proper separation of concerns and scalability.

Objectives

• Refactor the controller module in src/controller/
• Separate routing logic from request handling
• Implement worker management for background tasks
• Add input validation and sanitization
• Implement rate limiting and throttling
• Add authentication and authorization
• Ensure proper error handling and response formatting

Implementation Details

• Refactor route handlers to use the service layer
• Implement middleware for common concerns (auth, logging, etc.)
• Create worker management for background tasks
• Add input validation using a schema validation library
• Implement rate limiting based on client identifiers
• Add authentication and authorization checks
• Standardize error responses and status codes

Acceptance Criteria

• Controllers delegate business logic to services
• Routes are properly organized and documented
• Workers are managed efficiently with proper lifecycle
• Input validation prevents invalid requests
• Rate limiting protects against abuse
• Authentication and authorization are properly enforced
• Error responses are consistent and informative

Dependencies

• Error handling system
• Service layer implementation
