feat: configure CI/CD with Forgejo Actions

- Add Forgejo workflow for automated build and deploy
- Build creates dist/ from public/ then adds Vue app build
- Configure Vite to build to dist/assets/dist with fixed filenames
- Deploy entire dist/ directory to production via FTP
- Add workflow documentation with FTP setup instructions

The workflow mirrors the GitLab CI approach: dist/ is created during build
and synchronized to production root on every push to main.
