feat: Ozonetel V3 dial endpoint, worklist query fixes

- Switch outbound dial to /CAServicesV3/mdlConnection.php (tbManualDial)
- Use both Apikey + Basic Auth headers matching Ozonetel toolbar pattern
- Auto-login agent before dial attempt
- Dial controller returns 502 (not 401) for Ozonetel errors to prevent session logout
- Fix worklist: remove non-existent callId from followUp query
- Fix worklist: use unquoted MISSED enum, remove callerNumber subfield issue
- Worklist controller resolves agent name from platform currentUser API
