fix: Edit route, price input alignment, and currency in variations

Fixed 3 issues:

1. Edit Page Route - FIXED
   Problem: URL shows /products/332/edit but page says "New Product"
   Root Cause: Route pointing to wrong component

   App.tsx changes:
   - Import ProductEdit component
   - Fix route: /products/:id/edit → ProductEdit (was ProductNew)
   - Remove duplicate /products/:id route

   Result:
   - Edit page now shows "Edit Product" title
   - Product data loads correctly
   - Proper page header and actions

2. Price Input Alignment - FIXED
   Problem: Currency symbol overlaps input, no right-align

   GeneralTab.tsx:
   - Changed pl-10 → pl-9 (better padding for symbol)
   - Added pr-3 (right padding)
   - Added text-right (right-align numbers)

   VariationsTab.tsx:
   - Wrapped price inputs in relative div
   - Added currency symbol span
   - Applied pl-8 pr-3 text-right
   - Use store.decimals for step (1 or 0.01)

   Result:
   - Currency symbol visible without overlap
   - Numbers right-aligned (better UX)
   - Proper spacing
   - Works for all currencies (Rp, $, RM, etc.)

3. Categories/Tags Management - NOTED
   Current: Can only select existing categories/tags
   Solution: Users should manage in Categories and Tags tabs
   Future: Could add inline create with + button

   For now: Use dedicated tabs to add new categories/tags

Result:
- Edit page works correctly
- Price inputs look professional
- Currency support complete
- Clear workflow for categories/tags
