Camb AI + Vapi Integration

Keep Camb AI and Vapi aligned: use one app's ai actions to perform the other's.

Example: use Camb AI's "Create a Text-to-Sound Task" action to perform Vapi's "Attach and Ingest a File" action. Camb AI has 10 actions (including Create a Text-to-Sound Task, Create a Transcription, and Create Text to Speech); Vapi has 133 actions (including Attach and Ingest a File, Cancel Simulation Run, and Cancel Simulation Run Item).
