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
