Checklist

• This change requires a documentation update, included: Dify Document
• I understand that this PR may be closed in case there was no previous discussion or issues. (This doesn't apply to typos!)
• I've added a test for each change that was introduced, and I tried as much as possible to make a single atomic change.
• I've updated the documentation accordingly.
• I ran make lint && make type-check (backend) and cd web && pnpm exec vp staged (frontend) to appease the lint gods

Validation performed:

• pnpm -C web exec eslint --fix features/deployments/detail/deployment-sidebar.tsx
• pnpm -C web type-check
• Attempted pnpm -C web exec vp staged, but it failed because vite.config.ts does not define a staged config in this checkout.
