Add driver document review and staff onboarding

Driver documents: paged list from auth/driver/drivers_pending_list.php, a
detail panel showing each uploaded document as a thumbnail linking to the
full image, and activation via Admin/driver/updateDriverFromAdmin.php. The
confirmation states how many documents were reviewed and warns explicitly
when a captain has none on file, since approving then activates an
unverified account.

Details are requested as a POST body. The mobile app calls this endpoint as
GET "?id=", which filterRequest() never reads, so its detail lookup cannot
be receiving an id at all.

Staff: pending admin/service accounts with per-account activation via
Staff/activate.php, the employee list, and a creation form posting to
Staff/add.php. Administrator accounts are offered only to super admins,
matching add.php's own check; passwords are rejected below 8 characters and
cleared from the form after submission.

Both screens mask phone numbers for plain admins and never render
token/password/fingerprint fields.

Also stop .btn-primary stretching to full width when used inline in a card
header — it is styled for the login form.
