fix: add relative imports to the dependency list in deploymentUI (#8548)

* prepare sqlx

* Add relative imports to getDependencies of deployUI

* nit

* fix: correct get_imports doc comment, add tracing, use Set for dedup

- Fix copy-pasted doc comment on get_imports (said "get dependents")
- Add tracing::debug to get_imports handler to match get_dependents
- Use Set for O(1) duplicate detection in deploy dependency traversal
