Add REST API v1 endpoints and legacy catalog handling for pkg6depotd

- Expanded repository structure by introducing methods for fetching legacy catalogs, catalog file paths, and repository info.
- Added new REST API v1 endpoints for catalog, manifest, file, and publisher handling.
- Implemented `publisher` handler module with `get_publisher_v0` and `get_publisher_v1` methods to retrieve publisher details in pkg5 format.
- Updated `integration_tests` to validate new endpoints and ensure compatibility with legacy and modern catalog/manifest handling.
- Removed unused dependency `walkdir` and refactored test cases for clarity and efficiency.
