fix(api): add requireRoleOrSuperUser OR-guard, replace AND-stacking on staff routes

CRITICAL: requireRole("manager") + requireSuperUser() stacked = AND logic,
blocking all non-super-user managers from staff CRUD.

Added requireRoleOrSuperUser() OR-guard middleware. Staff write routes now use
the combined guard: manager role OR super-user flag grants access.
