The buildRegistryAuths function was inserted between the writeLogsToFile
doc comment and the writeLogsToFile function body, causing Go to treat
the writeLogsToFile comment as part of buildRegistryAuths godoc.
Move the writeLogsToFile comment to sit directly above its function,
and keep only the buildRegistryAuths comment above buildRegistryAuths.
Add per-app registry credentials that are passed to Docker during image
builds, allowing apps to use base images from private registries.
- New registry_credentials table (migration 007)
- RegistryCredential model with full CRUD operations
- Docker client passes AuthConfigs to ImageBuild when credentials exist
- Deploy service fetches app registry credentials before builds
- Web UI section for managing registry credentials (add/edit/delete)
- Comprehensive unit tests for model and auth config builder
- README updated to list the feature
