* fix: use relative redirects in booking confirmation routes to fix localhost redirect issue
When Cal.com runs behind a reverse proxy, request.url may return the internal
server URL (localhost:3000) instead of the external URL. This causes users to
be redirected to localhost after confirming bookings via email links.
This fix changes the redirect URLs from using url.origin (which could be
localhost) to using relative URLs via new URL(path, request.url). This ensures
the browser resolves the redirect against whatever domain the user actually
requested, fixing the issue for self-hosted deployments behind proxies.
Fixes#20358

* test: add tests for booking confirmation redirect URL construction
Add unit tests for verify-booking-token and link API routes to ensure:
- Redirect URLs preserve the request origin (not hardcoded localhost)
- Redirect URLs use the correct booking path (/booking/{uid})
- Error messages are properly encoded in query params
- POST handler returns correct 303 status code
These tests verify the fix for #20358 where users were redirected to
localhost:3000 instead of the proper production URL after confirming
bookings via email links.
