- Admin changelog page now fetches releases live from the public Gitea
API (https://gitea.kalekber.cc) instead of a baked releases.json file
- Remove /static/releases.json from ui/.gitignore (no longer generated)
- Add Gitea to admin sidebar external tools (admin_nav_gitea i18n key,
all 5 locales, compiled paraglide JS force-added)
- release.yaml: remove 'Fetch releases from Gitea API' step; extract
release title and body from the tagged commit message for Gitea releases
Replace runtime Gitea API fetch with fs.readFileSync of releases.json,
which CI writes to ui/static/ before the Docker build context is sent.
Eliminates prod→homelab network dependency for the changelog page.
