Implement vendor visibility filter for products: add vendorVisible field, filter list interface, add UI toggle

- Add vendorVisible field to Product entity (TINYINT in DB)
- Filter list results: non-vendor users only see vendorVisible=false/NULL products
- Vendor users (teacher role or approved vendorStatus) see all products
- Add vendorVisible toggle to product edit form in admin
- Add isVendorUser/isGuest helper methods in ProductService
- Add vendor_visible column to schema.sql with migration
- Frontend: product edit form with switch to enable/disable vendor-only visibility
