Manager Console Fixes

Problem

Restaurant owners and clerks could not access the manager console. Multiple API routes had UUID vs numeric ID mismatches in authorization checks.

Fixes by Route

/api/admin/restaurants/route.ts

• restaurants table has no legacy_numeric_id column — replaced with id
• owner_user_id is UUID but was queried with numeric legacy_numeric_id — switched to auth.uid
• Added assignments table lookup so assigned restaurants (not just owned) are found

/api/admin/orders/route.ts

• userHasAssignmentForRestaurant was querying UUID column with numeric ID — fixed to use auth.uid
• Owner check was comparing UUID with number — fixed to compare UUIDs

/api/admin/orders/[orderId]/route.ts

• Same UUID fix for assignment lookup in both GET and PATCH handlers

/api/order-detail/[orderId]/route.ts

• Response was missing firestore_id on order object — added firestore_id: String(order.id)
• Same UUID fix for assignment lookup

SWR Performance Fix

Page transitions were very slow due to aggressive SWR config in src/lib/swrConfig.ts:

This means navigating back to a previously visited page shows cached data instantly instead of a loading spinner, and switching browser tabs no longer triggers refetches.
