feat(workshop): vehicles must be assigned to a customer

- Added customer_id column to fleet_vehicles with FK to customers.

- Enforced customer_id on create_vehicle endpoints (workshop and fleet).

- New vehicle modal now requires a selected customer and stores customer_id.

- Migration v4.13 applied to all tenants.
