fix(ci): Add runtime-base back to build job needs

- build job accesses needs.runtime-base.outputs.image_ref, so runtime-base must be in needs
- Added always() condition to ensure build runs even if runtime-base is skipped
- Outputs will be empty if runtime-base was skipped, which is handled gracefully
