- Rename NewVolumeHelperImplWithCache to NewVolumeHelperImplWithNamespaces
- Move cache building logic from backup.go into volumehelper
- Return error from NewVolumeHelperImplWithNamespaces if cache build fails
- Remove fallback in main backup path - backup fails if cache build fails
- Update NewVolumeHelperImpl to call NewVolumeHelperImplWithNamespaces
- Add comments clarifying fallback is only used by plugins
- Update tests for new error return signature
This addresses review comments from @Lyndon-Li and @kaovilai:
- Cache building is now encapsulated in volumehelper
- No fallback in main backup path ensures predictable performance
- Code reuse between constructors
Fixes#9179
