AWS Transcribe + Taximail Integration

Wire AWS Transcribe's ai events into Taximail's communication actions so handoffs stay automatic.

Example: when Taximail's "Watch Events" fires, WEXTL can "Create Vocabulary" in AWS Transcribe. AWS Transcribe has 12 actions (including Create Vocabulary, Create Vocabulary Filter, and Delete Transcription Job); Taximail has 22 actions (including Create a Campaign, Create a List, and Delete a Campaign).
