Notes:
- Using a webhook sink in Sequin
- Connected to this here phoenix app
- ngrok to http 4000
- http endpoint in sequin pointed to ngrok address
- Manually constructed products-sink.wit
- This could and should be automated based on postgres schema plus sequin specifics
- implemented in products-sink.js
- wasmex process starts in application.ex
- webhook_controller hands off to wasmex
- these last 2 things get replaced by proper wasm component sink
