release readiness

[tohuwabohu-io]

• set up container registry
• add release workflow
• build and publish librefit-service and librefit-web docker images

I experimented with GraalVM and initially planned to use the native or native-micro image. Sadly that's not possible atm.

Some insights:

• flyway migration added: https://flywaydb.org/ the quarkus plugin provided some convenience
• flyway has limitations for reactive datasources, so both the JDBC and the reactive-pg driver need to be present. This causes some warnings on startup
• flyway needs some workarounds. See io.tohuwabohu.util.FlywayMigration.kt

Those workarounds cause troubles with the migration during runtime. I tried some tricks but in the end ended up in a situation where I'd have to manually maintain a migration SQL list in the application.properties file just to make a really wonky-looking workaround for other workarounds work.

Other stuff:

• updated various dependencies for librefit-web
• updated node version from 19.something -> 21.7.0
• added adapter-node to librefit-web and dockerized the SvelteKit app
• changed PUBLIC_API_BASE_PATH -> API_BASE_PATH and import from $env/dynamic/private. That way the service URL can be changed for each deployment

For testing the whole stack, a new docker-compose file has been created in deployment/test-delivery

It's a little bit rough on the edges, but that's enough for the first deployment.
