fix(GRO-635): implement groomer data isolation in appointmentGroups, groomingLogs + batherStaffId conflict check

- appointmentGroups: Hono<AppEnv>() + groomer isolation on all 5 endpoints
- groomingLogs: Hono<AppEnv>() + groomer isolation on GET, POST, DELETE with appointmentId preserved
- appointments: batherStaffId conflict checks in POST and PATCH handlers
- Non-groomer roles retain full access
