various fixes for Docker

[beorn]

• graceful exit for all servers
• Dockerfile for blocksuite (same as auth-express)
• move dependencies from root package.json to demos as appropriate
• use console.log for logging (didn't seem like print logging system worked and it wasn't used everywhere)
• output config variables on startup (for tracing/debugging)
• some renames - but could do more (I like authn for authentication and authz for authorization)
• using "standard" image for minio container
• using trust mode for postgres container (doesn't expose a public port, so safe enough for testing)
• the only thing that needs to be put in your .env is the auth_*_keys

Some questions

• It would be nice to have a prettierrc setup so code formatting could be used and be consistent with what you use
• The YAML anchors doesn't work across includes - so ./demos/*/compose.yaml can't get the anchors from ./compse.yaml - perhaps it'd be useful to use Docker configs instead for this
• Is rollup really needed, at least in the root package.json?
• I still think it'd be nice to do a monorepo with separate packages - and could then use something like ultra-runner (or turborepo) to run multiple scripts at the same time with colorized log output

@beorn you shouldn't use npm install either, instead use npm ci to make use of the package-lock.json ...
