fix: dispose creates inbound Call record, webhook enriches — eliminates UCID mismatch + timing race

Root cause: CDR webhook fires 5s after dispose, stores monitorUCID.
Frontend has agent-side UCID from SIP. They never matched → disposition
not persisted, agent call history empty.

Fix:
- Dispose endpoint now creates Call records for ALL answered calls
  (inbound + outbound), not just outbound. Record gets agent-side UCID
  + correct disposition immediately.
- Webhook checks if Call record already exists (by agent UCID via
  monitorUCID→agentUCID mapping). If found, enriches with recording
  URL, agent chain name, CDR timing. If not found, creates as fallback.
- SupervisorService stores UCID mapping from real-time events (which
  carry both UCIDs). Auto-expires after 10 minutes.

Verified: UCID-MAP logged, dispose creates record, webhook enriches
without duplicating. DB shows correct agent UCID + disposition + recording.
