Issue Description

Originally reported by @mman in #7210 (comment).

the PagesRouter must be mounted on /apps otherwise it will break the password reset logic (since UserController.js seems to be ignoring the pages router mount path.

This is true for password reset and email verification.

Steps to reproduce

1. Use experimental pages router
2. Set custom pages endpoint that is not apps
3. Request a password reset link --> link is incorrect

Actual Outcome

Link is incorrect because it contains the default endpoint apps.

Expected Outcome

Link should contains the custom pages.
