fix(wanda): prioritize local Docker images before falling back to remote registry

[Lucas61000]

Prioritize locally available Docker images when resolving base images, falling back to remote registry only if not found locally.

Code Review

This pull request modifies the image resolution logic in resolveBases to attempt local resolution before falling back to a remote registry. Feedback suggests using resolveDockerImage instead of resolveLocalImage to maintain consistency and ensure the configured Docker environment is respected. Additionally, it is recommended to remove the local resolution error from the final error message to reduce noise, as a local failure is expected in this fallback flow.
