fix: remove remaining pipelock references missed in prior pass

- test_supervise.py: drop TOOL_PIPELOCK_BLOCK import; update TOOLS
  assertion to match the 3-item tuple (egress, capability, list-egress)
- test_supervise_server.py: remove pipelock from tools-list assertion,
  fix test_rejected_response_sets_isError to use capability-block
- contrib/claude and contrib/codex: remove tls_passthrough=True from
  EgressRoute constructors (field removed with pipelock)
- test_egress.py: drop tls_passthrough parameter from _provider_route,
  remove tls_passthrough-only tests, fix EgressRoute constructions
- test_agent_provider.py: drop route.tls_passthrough assertions
