refactor: simplify gitea config to use owner/repo format

- Remove separate GITEA_OWNER config, use owner/repo format everywhere
- Add _parse_repo() helper to extract owner and repo from combined string
- Update plugin.json schema: file -> source, author as object
- Remove redundant configuration section from cmdb-assistant plugin
- Simplify gitea_client.py by removing excessive docstrings
