## What kind of change does this PR introduce?
Bug fix / UX improvement for the Vercel Deploy Button create-project
interstitial.
## What is the current behavior?
On the Vercel create-project step, the organization picker is locked
(correct — the integration is bound to that org) and Cancel is hidden.
If the org can't create a free project (member free-project limits),
users hit a dead end: Upgrade may not help, and there's no way out of
the popup.
Also includes a small capitalisation nit on the Vercel install page.

/> |
## What is the new behavior?
- Replaces `hideCancelButton` with `cancelAction: 'studio' | 'vercel' |
'hidden'`
- Vercel create flow shows **Return to Vercel**, which redirects to the
install `next` URL (closing the popup cleanly)
- Free-project-limit admonition adds a Vercel-only hint pointing at that
button: “Or return to Vercel and restart with a different organization.”
- Main `/new` Cancel behaviour is unchanged
- Org picker stays disabled
## Additional context
Org switching mid-create is intentionally not allowed. That would orphan
the Vercel install. Returning to Vercel is the safe escape hatch so
users can restart Deploy Button with another org, or free a project slot
/ upgrade and try again.
## To test
As far as I can tell, this is impossible to test on prod. Shortly after
merge though, you could test the following:
- [ ] Happy path: create still works; Return to Vercel is secondary and
does not block submit
- [ ] Free-limit blocked org: Create disabled, Return to Vercel visible
and redirects to `next`
- [ ] Main `/new`: Cancel still goes to last org / organizations

## Summary by CodeRabbit
- **New Features**
- Enhanced project creation flow for Vercel: when a valid return
destination is available, users can choose **“Return to Vercel”**.
- Added additional messaging in the free-project-limit warning to guide
users back to Vercel and restart with a different organization (when
applicable).
- **Bug Fixes**
- Improved cancel behavior and routing consistency by only enabling
Vercel return when the destination is valid.
- **Style**
- Updated the Vercel integration interstitial title capitalization for
consistency.

## Testing
- Open the deploy preview or staging URL for
`/dashboard/integrations/vercel/acme-production/marketplace/choose-project`
with callback params from a real Vercel Marketplace install redirect
(see _Vercel_ subheading below).
### Vercel
- Run through the [install
flow](https://github.com/supabase/supabase/pull/47550) on a real project
until you get to the project connection screen, copy the url and paste
into staging preview
