refactor(api): reorder imports and update code formatting across repository endpoints

- Reordered actix-web imports to standardize import order
- Reordered crate module imports to follow alphabetical ordering
- Updated function calls to use multi-line formatting for better readability
- Standardized blank lines around documentation comments
- Applied consistent formatting to response handling methods
- Normalized import organization across all repository-related API files
- Improved code consistency and maintainability through standardized formatting
- Applied formatting updates to all repository endpoint implementations
