Danny White 0324f3422a chore(studio): polish vercel deploy-button new project interstitial (#48113) ...

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Studio UI polish for the Vercel deploy-button new-project connect flow
(DEPR-616 follow-up).

## What is the current behavior?

- Deploy-button project creation still used
`VercelIntegrationWindowLayout` (top bar + Docs/Support footer) while
install and choose-project already use shared `InterstitialLayout`
- The remove-integration note sat as a floating admonition above the
form
- Advanced / internal-only config sections could show double dividers,
and the Oriole radio bottom border could clip inside the collapsible

## What is the new behavior?

- Deploy-button new-project uses `InterstitialLayout` with
`VercelIntegrationLogo` and `VercelIntegrationFooter`, matching the
other Vercel connect surfaces
- Regular `/new` project creation is unchanged; Panel chrome is only
flattened when `isVercelIntegrationFlow` is set
- Removes unused `VercelIntegrationWindowLayout` /
`IntegrationWindowLayout`
- Fixes Advanced/Internal-only dividers and collapsible border clipping

## Additional context

### Testing

With Studio running locally and while signed in:

1. Open
`http://localhost:8082/integrations/vercel/<your-org-slug>/deploy-button/new-project`
2. Confirm the interstitial card: Vercel + Supabase logo pair, “Create a
new project” title, form fields, and the muted remove-integration footer
under the card
3. Confirm there is no old window chrome (no “Marketplace Connector” /
“Deploy Button” top bar, no Docs/Support footer)
4. Optionally submit and confirm project creation still works
5. Spot-check `/new` to confirm the normal project creation form is
unchanged

If you have advanced config enabled, expand Advanced Configuration and
confirm single dividers (not doubles) and that the Oriole option’s
bottom border is not clipped.
