Subject: [PATCH] fix(kokoros): implement face_verify and face_analyze trait
 stubs (#9499)

The backend.proto was updated to add FaceVerify and FaceAnalyze RPCs
(face detection support), but the Rust KokorosService was never updated
to match the regenerated tonic trait, breaking compilation with E0046:

    not all trait items implemented, missing: `face_verify`, `face_analyze`

Stubs both methods as unimplemented, matching the pattern used for the
other RPCs Kokoros does not support.
