refactor: Update service and repository methods to use context

- Refactored multiple service and repository methods to accept context as a parameter, enhancing consistency and enabling better control over request lifecycles.
- Updated handlers to utilize context in method calls, improving error handling and performance.
- Cleaned up Dockerfile by removing unnecessary whitespace.
