fix(ci): fix lint, schema, test, and migration issues for release

- Fix PLR0915 lint: extract _create_a2a_client_with_headers and _set_message_context_id helpers in a2a_protocol/main.py to reduce statement count below 50
- Fix JSON schema: add supports_none_reasoning_effort and supports_xhigh_reasoning_effort to test_utils.py schema definition
- Fix gpt-5.1 temperature test: change temperature=0.6 to temperature=1 (gpt-5.1 supports any temperature only when reasoning_effort='none'; temperature=1 is always valid)
- Add Prisma migration for LiteLLM_AgentsTable static_headers/extra_headers columns
- Sync litellm/proxy/schema.prisma with root schema.prisma
