On gateway restart, persisted non-terminal calls are now verified with
the provider (Twilio/Plivo/Telnyx) before being restored to memory.
This prevents phantom calls from blocking the concurrent call limit.
- Add getCallStatus() to VoiceCallProvider interface
- Implement for all providers with SSRF-guarded fetch
- Transient errors (5xx, network) keep the call with timer fallback
- 404/known-terminal statuses drop the call
- Restart max-duration timers for restored answered calls
- Skip calls older than maxDurationSeconds or without providerCallId
Address review feedback: log a warning when endCall fails on stream
disconnect instead of silently discarding the error.

When a Twilio media stream disconnects (e.g., caller hangs up or
network drops), the call object was left in an active state indefinitely.
This caused "stuck calls" that consumed resources and blocked new calls.
Now calls are automatically ended when their media stream closes,
matching the expected lifecycle behavior.

Address review feedback: log a warning when the stale call reaper
fails to end a call instead of silently discarding the error.

Adds a periodic reaper that automatically ends calls older than a
configurable threshold. This catches calls stuck in unexpected states,
such as notify-mode calls that never receive a terminal webhook from
the provider.
New config option:
staleCallReaperSeconds: number (default: 0 = disabled)
When enabled, checks every 30 seconds and ends calls exceeding the
max age. Recommended value: 120-300 for production deployments.

Address review feedback: the in-memory deletion of initialMessage is
not persisted to disk, which is acceptable because a gateway restart
would also sever the media stream, making replay impossible.
