The last action still calling callClaudeApi directly. Now routes through
resolveAgent (task_type="policy_sensitivity") + checkGovernancePolicy +
callAgent, consistent with all other Phase 11 AI invocations. Adds
agentRegistrationId, tokensIn, tokensOut to the created AgentProposal and
handles blocked_by_policy the same way as the other 4 actions.
Remove callClaudeApi and its direct HTTP imports from
Application/Helper/Controller.hs — no longer referenced anywhere.
