Fix Docker builds, TS errors, and deploy config

- API: PHP 8.4, composer install --no-scripts + dump-autoload after COPY
- Admin: fix TS (Event.upload_password, unused router, api XSRF, window.open)
- Upload: Uppy v5 (hideProgressDetails, headers, destroy), unused watch, api XSRF
- Build script: loop over api/admin/upload, push :latest as well as VERSION
- Deploy: MySQL from docker.io, platform linux/amd64; README troubleshooting
