BigChange + Camb AI Integration

Wire BigChange's project management events into Camb AI's ai actions so handoffs stay automatic.

Example: when BigChange's "Watch Contacts" fires, WEXTL can "Create a Text-to-Sound Task" in Camb AI. BigChange has 10 triggers (including Watch Contacts, Watch Invoices, and Watch Jobs); Camb AI has 10 actions (including Create a Text-to-Sound Task, Create a Transcription, and Create Text to Speech).
