Fix compilation errors from SearchServer extraction

- Update NewLocalResourceClient to accept SearchServer parameter
- Add SearchClient methods to ResourceClient interface (client needs both)
- Fix directResourceClient to implement new interface with stub methods
- Update search_and_storage.go test to create SearchServer separately

This continues the work of extracting SearchServer from ResourceServer
to enable independent usage by storage.
