cleanup: remove junk files, fix broken servlet routes, add Payments nav

Deletions:
- Remove root junk: IoT Bay.zip (74MB), compile_log*.txt, test_output.txt
- Remove empty ProductController.java (0-byte file)
- Remove unused BrowseProductController.java (duplicate of BrowsePageController)
- Remove duplicate JSPs: dataManagement.jsp, manage-data.jsp

Routing fixes (@WebServlet annotations restored):
- CartController         → /cart, /cart/* (cart view + add-to-cart)
- OrderHistoryController → /orderhistory
- UserProfileController  → /api/profile
- ProductDetailsController → /product
- RegisterController     → /api/auth/register (matches register.jsp form action)

Navigation:
- header.jsp: add Payments link → /api/payment/history (F04 access)
