feat: add RedMesh test and job-start attestation submissions

[aledefra]

Summary

• split attestation submit flow into explicit RedMesh test attestation and RedMesh job-start attestation paths
• submit a one-time job-start attestation during launch_test
• keep pass-finalization best-effort test attestation submit with rate-limit behavior
• include packed execution_id (job_id) in job-start attestation payload
• include aggregated node_hashes derived from deterministic worker EVM address set

Notes

• tenant wallet remains R1EN_ATTESTATION_PRIVATE_KEY
• both attestation submits use SDK generic submit_attestation API
• PoAIManager active-node validation remains deferred to contract TODO flow

Validation

• python -m py_compile extensions/business/cybersec/red_mesh/pentester_api_01.py
