Three issues caused the port to remain bound after partial failures:
1. VoiceCallWebhookServer.start() had no idempotency guard — calling it
while the server was already listening would create a second server on
the same port.
2. createVoiceCallRuntime() did not clean up the webhook server if a step
after webhookServer.start() failed (e.g. manager.initialize). The
server kept the port bound while the runtime promise rejected.
3. ensureRuntime() cached the rejected promise forever, so subsequent
calls would re-throw the same error without ever retrying. Combined
with (2), the port stayed orphaned until gateway restart.
Fixes#32387

Twilio signs webhook requests using the URL without the port component,
even when the publicUrl config includes a non-standard port. Add a fallback
that strips the port from the verification URL when initial validation fails,
matching the behavior of Twilio's official helper library.
Closes#6334
Address Greptile review: externally-initiated outbound-api calls were
stored with hardcoded direction: "inbound". Now createWebhookCall accepts
a direction parameter so the CallRecord accurately reflects the event's
actual direction. Also skip inboundGreeting for outbound calls and add a
test asserting inbound direction is preserved.

Fixes#30900 — Calls initiated directly via the Twilio REST API
(Direction=outbound-api) were rejected as "unknown call" because
processEvent only auto-registered calls with direction=inbound.
External outbound-api calls now get registered in the CallManager
so the media stream is accepted. Inbound policy checks still only
apply to true inbound calls.

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.
