Summary

Fixes two issues causing the admin page (/admin) to render blank with TypeError: b.filter is not a function:

Appointments.tsx: Added r.ok checks before .json() on /api/clients, /api/services, and /api/staff fetches. Previously, 403/404 error responses had their JSON body (e.g. {error:"Forbidden"}) passed to state setters. Calling .filter() on a non-array object crashes the component. Now errors are thrown and caught by the existing .catch() handler, which sets the error state instead.
DevLoginSelector.tsx: Added userId: string | null to StaffUser interface and changed s.id → s.userId ?? s.id for the dev login identifier. Pre-migration staff records have userId = null, so the nullish coalescing correctly falls back to staff.id (the PK). Post-migration, the API returns userId and that is used directly.

Test plan

Dev login as a staff user (e.g. Devon Williams) → should land on /admin without blank page
Verify appointments, clients, services, staff all load correctly
Verify error state is shown (not blank page) when API returns 403

## Summary Fixes two issues causing the admin page (`/admin`) to render blank with `TypeError: b.filter is not a function`: - **Appointments.tsx**: Added `r.ok` checks before `.json()` on `/api/clients`, `/api/services`, and `/api/staff` fetches. Previously, 403/404 error responses had their JSON body (e.g. `{error:"Forbidden"}`) passed to state setters. Calling `.filter()` on a non-array object crashes the component. Now errors are thrown and caught by the existing `.catch()` handler, which sets the error state instead. - **DevLoginSelector.tsx**: Added `userId: string | null` to `StaffUser` interface and changed `s.id` → `s.userId ?? s.id` for the dev login identifier. Pre-migration staff records have `userId = null`, so the nullish coalescing correctly falls back to `staff.id` (the PK). Post-migration, the API returns `userId` and that is used directly. ## Test plan - [ ] Dev login as a staff user (e.g. Devon Williams) → should land on `/admin` without blank page - [ ] Verify appointments, clients, services, staff all load correctly - [ ] Verify error state is shown (not blank page) when API returns 403 cc @cpfarhood

LGTM - Fix correctly adds r.ok checks to prevent non-JSON error bodies from crashing the admin page. DevLoginSelector userId fallback is also correct.
