Erich Blume ffa8727660 Adopt commit-based container tags (#232)
## Summary
- Replace git-tag-triggered container builds with path-based triggers on main and workflow_dispatch
- Image tags now encode upstream app version + commit SHA (`vX.Y.Z-<sha>`) for full traceability
- Replace `container-tag-and-release` task with `container-build-and-release` (dispatches workflows via Forgejo API)
- Update dagger `publish()` to accept `commit_sha` parameter
- Update all docs and references to the new workflow

## Deployment and Testing
- [ ] Merge to main
- [ ] `mise run container-build-and-release <name>` for each container to populate new-format tags
- [ ] Verify tags in registry via `mise run container-list`
- [ ] Existing images untouched — old tags remain available

# Dockerfile container build workflow
# Triggers on pushes to main that modify containers/*, or via manual dispatch.
# Detects which containers changed, extracts version from CONTAINER_APP_VERSION,
# and publishes with commit-SHA-based tags: vX.Y.Z-<sha>
