feat(taiko-client): clear zk proof backlog before fallback

[YoGhurt111]

Summary

• add Raiko prover admin APIs for GET /v3/prover/status and POST /v3/prover/clear
• clear local proof buffers/caches once and resend queued proof submissions after the zk prover reports clean
• add tests for Raiko prover admin calls and one-time local clear/resend behavior

Validation

/usr/local/go/bin/go test ./packages/taiko-client/prover/proof_producer -count=1
/usr/local/go/bin/go test ./packages/taiko-client/prover/proof_submitter -count=1

Both pass locally. The output includes existing macOS linker warnings from libbls384_256.a.
