feat: CC agent features, live call assist, worklist redesign, brand tokens

CC Agent:
- Call transfer (CONFERENCE + KICK_CALL) with inline transfer dialog
- Recording pause/resume during active calls
- Missed calls API (Ozonetel abandonCalls)
- Call history API (Ozonetel fetchCDRDetails)

Live Call Assist:
- Deepgram Nova STT via raw WebSocket
- OpenAI suggestions every 10s with lead context
- LiveTranscript component in sidebar during calls
- Browser audio capture from remote WebRTC stream

Worklist:
- Redesigned table: clickable phones, context menu (Call/SMS/WhatsApp)
- Last interaction sub-line, source column, improved SLA
- Filtered out rows without phone numbers
- New missed call notifications

Brand:
- Logo on login page
- Blue scale rebuilt from logo blue rgb(32, 96, 160)
- FontAwesome duotone CSS variables set globally
- Profile menu icons switched to duotone
