Get Voice Capacity

Concurrent AI calls (RO-181): the workspace's limit in effect (the platform's per-workspace limit, lowered by the workspace's own setting), its calls ringing or in progress, its dials waiting for a free slot, and whether the platform-wide limits (all workspaces, voice workers, SIP channels, speech-to-text / LLM / text-to-speech capacity) leave room now. Every dial is admitted against these limits right before it is placed; a dial without a slot waits and is tried again (it never fails for lack of capacity until it has waited ``VOICE_ADMISSION_MAX_WAIT_SECONDS``).
