Improve shopping mode and flatten nav bar

Shopping mode:
- Click to complete items (deletes user items, hides external items)
- Add print button with compact two-column print layout
- Fix CSRF token for HTMX requests
- Fix input clearing with proper htmx:afterRequest handler
- Remove "Quick Add" store option, require valid store

Navigation:
- Replace dropdown menu with flat nav showing all tabs
- Remove unused dropdown JS

Tests:
- Add TestHandleShoppingModeComplete for user and external items
