Build inventory frontend and stock management features

- 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
- Product-supplier links and stock receipts in seed data
- Price history seed data simulating cost increases over past year
- 37 API tests covering categories, suppliers, products, units,
  product-suppliers, and stock receipts
- alert-dialog and checkbox UI components
- sync-and-deploy.sh script for rsync + remote deploy
