## What kind of change does this PR introduce?
Impending feature addition. Resolves DEPR-340.
## What is the current behavior?
We don’t have any platform webhook support.
## What is the new behavior?
This puts the scaffolding for platform webhooks **behind a feature
flag**. The content is currently UI-only (with mock data and a
[temporary tracking
file](8adadc61f5/apps/studio/components/interfaces/Platform/Webhooks/DEPR-340-backend-integration-tracker.md)).
Merging this in lets us work incrementally from here on.
