[codex] implement outbound quick calls

[rahuliitk]

Summary

• Add server-side outbound quick-call dispatch that validates the selected caller ID belongs to the active/configured agent, resolves provider/SID from the database, and persists LiveKit dispatch metadata.
• Add runtime agent-config fallback by agent ID for outbound jobs, plus metadata-driven outbound first-message/system-prompt overrides in the AI worker.
• Add a console /outbound quick-call screen with assigned-number selection and API mutation wiring.

Validation

• pnpm --filter server exec tsx --test tests/outbound/outbound-call.schema.test.ts tests/outbound/outbound-call.service.test.ts tests/outbound/outbound-call.route.test.ts
• apps/ai/.venv/bin/python -m unittest discover apps/ai/tests
• pnpm --filter server check-types
• pnpm --filter console exec tsc --noEmit
• pnpm --filter console lint (0 errors, existing warnings remain)
• find tests -name '*.test.ts' -print0 | xargs -0 pnpm exec tsx --test from apps/server
• pnpm build
• Browser smoke: unauthenticated http://localhost:3100/outbound redirects to /login with no runtime console errors.

Notes

• I did not place a live PSTN test call because there was no known user-controlled destination number available, and I avoided calling arbitrary/customer numbers.

Live outbound verification update:

• Created LiveKit outbound trunk ST_7mnYLU6NUMKV for Twilio domain quickvoice-livekit.pstn.twilio.com, restricted to +16812696313.
• Added/attached a dedicated Twilio SIP credential list to the existing QuickVoice LiveKit Elastic SIP trunk, then updated the LiveKit trunk with matching SIP auth.
• Ran this PR's outbound service orchestration locally against real LiveKit/Twilio and this PR's AI worker under a unique agent name.
• Controlled destination: +918274925985.
• Final live call result: Twilio status completed, direction trunking-terminating, duration 26s, price $0.06590, from +16812696313.
• The PR worker logs showed outbound metadata was applied: the brief test first message and live-test system prompt overrode the agent's saved default prompt for the outbound job.

Production config note: ECS task definition currently has LIVEKIT_SIP_OUTBOUND_TRUNK_TWILIO_ID set to placeholder text. Deploying this PR should also set LIVEKIT_SIP_OUTBOUND_TRUNK_TWILIO_ID=ST_7mnYLU6NUMKV for quickvoice-server. Telnyx remains unwired unless/until a Telnyx LiveKit outbound trunk is provisioned.

Outbound UI QA/polish update:

• Polished /outbound quick-call UI to show carrier/provider context, friendly line names, all assigned caller IDs, inline started-call feedback, and a disabled submit state until the recipient number is present.
• Verified the real route with a local authenticated mock API for session, agents, numbers, and quick-call submit.
• Interaction tested: /outbound -> fill recipient, name, first message, system prompt override -> Start call -> success toast and inline started-call message.
• Verified submitted payload included agentId, phoneNumber, fromNumber, username, firstMessage, and systemPrompt.
• Browser checks: desktop screenshot, narrow mobile screenshot, mobile action/ready-lines scroll check, and console error check all clean.
• Commands run: pnpm --filter console exec tsc --noEmit, pnpm --filter console lint (0 errors, existing warnings only), pnpm --filter console build, git diff --check.
