Implement bridged forwarding with agent call control features

Browse Source 
Major enhancement to workflow forwarding that solves voicemail issues and adds agent call control capabilities.

Key improvements:
- Converted direct forwarding to bridged forwarding to avoid self-call voicemail issues
- Added DTMF-based agent features during calls:
  * *9 - Hold/Unhold customer
  * *0 - Start/Stop call recording
  * *5 - Transfer to another extension
  * *1 - Mute/Unmute (placeholder for future conference mode)
- Added webhook handlers for agent features and forward results
- Agent features URL attached to Number elements for DTMF detection
- Continuous DTMF listening during active calls
- Proper call leg detection for hold/resume operations

Technical details:
- Added /agent-features webhook for DTMF capture
- Added /agent-action webhook for processing commands
- Added /forward-result webhook for handling dial outcomes
- Modified append_twiml_element to preserve Number attributes (url, method)
- Enhanced logging throughout for debugging

This eliminates the issue where calling yourself would go straight to voicemail and provides professional call control features for agents.
