## What kind of change does this PR introduce?
Feature
## What is the current behavior?
- Platform webhooks have a ‘tap target on tap target’ pattern with
`DropdownMenu` being on top of a clickable `TableRow`
- Misclicks are common (at least for me)
- @jordienr recently added the `hit-area` Tailwind plugin that helps
with misclicks
- https://github.com/supabase/supabase/pull/43636
## What is the new behavior?
- The aforementioned `DropdownMenu` in platform webhooks now uses
`hit-area` to avoid misclicks
- Design system documentation
- Extracted `hit-area` Tailwind plugin to shared packages so it can be
used in design-system as well as studio
