kestra/kestra:latest is ~500MB; the registry rejects the push.
The init container only needs to POST flow YAMLs to the Kestra REST API
(/api/v1/flows/import), which curl handles fine from a tiny alpine base.

Bind mounts don't work on the remote Portainer host since the files
aren't present there. Instead, Dockerfile.init copies the flow YAMLs
into a dedicated image (kestra/kestra:latest base) that is built in CI
and pulled by Portainer like the other images.
