fix(membership): phone validation on edit + missing spouse fee API

- Add phone_mobile format validation in MemberController::update()
  (was only validated in store(), allowing invalid data via edit)
- Add missing SpouseController::calculateFee() method that the route
  /api/spouses/calculate-fee pointed to (returned 500)
