- TanStack Router search params: `{} as Record<string, unknown>`
- API response pagination: proper typed interface
- DataTable column casts: remove unnecessary `as any`
- Function params and event handlers: use specific types
- Remove unused imports and variables in POS components
Frontend lint now passes with 0 errors and 0 warnings.

- Full inventory UI: product list with search/filter, product detail with
tabs (details, units, suppliers, stock receipts, price history)
- Product filters: category, type (serialized/rental/repair), low stock,
active/inactive — all server-side with URL-synced state
- Product-supplier junction: link products to multiple suppliers with
preferred flag, joined supplier details in UI
- Stock receipts: record incoming stock with supplier, qty, cost per unit,
invoice number; auto-increments qty_on_hand for non-serialized products
- Price history tab on product detail page
- categories/all endpoint to avoid pagination limit on dropdown fetches
- categoryId filter on product list endpoint
- Repair parts and additional inventory items in music store seed data
- isDualUseRepair corrected: instruments set to false, strings/parts true

- 37 API tests covering categories, suppliers, products, units,
product-suppliers, and stock receipts
- alert-dialog and checkbox UI components
