What kind of change does this PR introduce?

Feature

What is the current behavior?

The webhook endpoint details view shows all mock deliveries in a single table without pagination or sortable columns, which makes it a poor fit for the Data Table direction this surface will need once real server-backed pagination and filtering land.

What is the new behavior?

Moves the deliveries table onto TanStack table state, adds sortable column headers, keeps the existing delivery search, and preserves simple previous/next pagination controls at the bottom. The mock deliveries are also expanded so pagination and sorting can be exercised in both organization and project flows.

Additional context

This keeps the view on the Data Table path now, so swapping client-side pagination for manual/server pagination later is a smaller follow-up instead of another structural rewrite.

Verification:

• pnpm --filter studio exec vitest run components/interfaces/Platform/Webhooks/PlatformWebhooksEndpointDetails.test.tsx --coverage.enabled=false
• pnpm typecheck
