feat: Enhance dependency injection and service integration

- Updated main.go to initialize email service and include it in the dependency injection container.
- Refactored handlers to utilize context in service method calls, improving consistency and error handling.
- Introduced new service options for upload, security, and captcha services, enhancing modularity and testability.
- Removed unused repository implementations to streamline the codebase.

This commit continues the effort to improve the architecture by ensuring all services are properly injected and utilized across the application.
