Danny WhiteandJoshen Lim 69f3c43118 fix(studio): close Vercel create popup on cancel (#48371)
## What kind of change does this PR introduce?

Bug fix / UX polish.

## What is the current behavior?

Cancel on the Vercel create interstitial redirects to Vercel’s `next`
URL. That finishes the install flow and shows “Completing installation…”
/ “Installation complete”, even though the user cancelled. The Deploy
Button job still proceeds and fails. The button was also labelled
“Return to Vercel”, which read like an alternate success path.

## What is the new behavior?

- _Return to Vercel_ button now labelled **Cancel**
- **Cancel** closes the popup via `window.close()` (same honest abort as
manually closing the window)
- If the browser blocks programmatic close, Cancel is replaced by muted
fallback copy: “Close window to cancel” (`role="status"` /
`aria-live="polite"`)
- Cancel is left-aligned with `justify-between` when there’s no
additional-costs block; with costs, both actions stay on the right
- Removes the free-limit hint line about returning to Vercel (Cancel
makes that self-evident)
- Success path is unchanged: after create, we still redirect via `next`
- `/new` Cancel still navigates into Studio (`cancelAction: 'studio'`).
This is unchanged behaviour

## Additional context

Follow-up to #48311. Vercel’s `next` URL has no documented cancel/abort
status, so closing the popup is the correct escape hatch.

### To test

Full Deploy Button popup cancel can’t be verified on prod until this
merges. Locally:

1. Open Studio on this branch.
2. In `ProjectCreationFooter.tsx`, temporarily force the fallback:
   ```ts
   const [showCloseWindowHint, setShowCloseWindowHint] = useState(true)
   ```
3. Load create-project UI:
- Free org / no costs: Confirm Cancel is left, Create is right
(`justify-between`). With the forced hint, Cancel is replaced by “Close
window to cancel”.
- Paid org with additional costs: Confirm costs on the left; hint/Create
on the right.
4. Revert `useState` to `false`.
5. Optional: open a Vercel create interstitial URL in a normal tab (not
a popup), click Cancel. `window.close()` fails and the hint should
replace Cancel after ~100ms.
6. On `/new/[slug]`, Confirm Cancel still returns to the Studio
dashboard (not close-window).
