chore: CI/build improvements and version detection

- Rename GITEA_TOKEN to DEPLOY_TOKEN in release workflow
- Extract shared version detection into build-common.sh
- Use importlib.metadata for runtime version instead of hardcoded string
- Use PEP 440 parsing (packaging lib) for update version comparison
- Add packaging>=23.0 to dependencies
- Fix update banner close button alignment (CSS)
- Update CLAUDE.md with versioning docs and frontend rebuild notes
