feat: allow admins and coordinators to also be drivers

Add a "Driver" checkbox column to the User Management page. Checking it
creates a linked Driver record so the user appears in the drivers list,
can be assigned events, and enrolled for GPS tracking — without changing
their primary role. The DRIVER role checkbox is auto-checked and disabled
since being a driver is inherent to that role. Promoting a user from
DRIVER to Admin/Coordinator preserves their driver record.
