v0.5.0

TanStack Form + TanStack Table across admin CRUD pages

New dependencies

• @tanstack/react-form v1.28.3
• @tanstack/react-table v8.21.3

New files

File	Purpose
src/hooks/use-crud-mutation.ts	Generic mutation hook — invalidation, toasts, fully typed callbacks
src/components/ui/data-table.tsx	DataTable<T> — TanStack Table with sorting, responsive column hiding, CSV export, afterRows slot
src/components/ui/search-filter.tsx	Search input + colored filter buttons

Changes

• TanStack Form with Zod validation replaces manual useState forms on all 5 admin CRUD pages
• DataTable<T> replaces manual <Table> rendering — 3-way sort toggle, mobile column hiding, timestamped CSV export
• useCrudMutation eliminates repetitive useMutation + invalidateQueries + toast boilerplate
• SearchFilter replaces repeated search + dropdown filter patterns
• Input extended with optional label and error props (backward-compatible)

Refactored pages

• products — form, table, mutations, search/filter, CSV export
• customers — same
• orders — edit+delete only, no create
• payment-methods — simple CRUD
• cashier — DataTable with afterRows for inline form, edit dialog with useForm

Fixes

• useCrudMutation now correctly invalidates tRPC queries after create (#17)
