feat: send disposition to sidecar with UCID for Ozonetel ACW release

- Store UCID from outbound dial API response in sipCallUcidAtom
- Replace direct createCall GraphQL mutation with sidecar /api/ozonetel/dispose
- Remove agent-ready call from handleReset (no longer needed)
- Clear UCID on dial error and call reset
