fix(docker): Make conduit own default db path
When a user mounts a volume into the default volume path,
it uses the permissions and ownership from the host volume.
In most cases, this is 1000:1000, which it also uses on the inside.

If you don't mount a volume though (e.g., for testing), conduit cries:
“The database couldn't be loaded or created.”

This fix chowns the default db dir to remedy this.

# It is mostly based on the normal Conduit Dockerfile, but adjusted in a few places to maximise caching.
