Squash-merge of PR #28 from @denis-ev. All three review blockers addressed: encryption key management documented, string truncation replaced with skip+warn validation, and undefined return on duplicate merge fixed with proper 500. Local test stack verified against cloned prod DB — migrations, new features, and backend all clean.
Adds a GitHub Actions workflow that builds and pushes backend and nginx
images to GitHub Container Registry on every merge to main and on
releases. Adds docker-compose.ghcr.yml for end users who want to deploy
without cloning the repo, and updates the README with Quick Deploy
instructions alongside the existing build-from-source guide.
