Package Updates

Changed files: only package.json and package-lock.json in the app and the manager.
Main versions:
Next.js: 16.2.12 (app) and 16.3.4 (manager) → 16.4.2 in both.
React and React DOM: 19.3.1.
Prisma: 7.10.1, including the client and the MariaDB adapter.
Smaller bumps: mariadb 3.5.4, image-size 2.0.4, postcss, zod, lucide-react, react-hook-form, the Radix packages and Playwright.
Verified: typecheck and lint are clean. All 420 app unit tests, 198 manager tests and 345 integration tests on MySQL 8 pass. The Prisma migrations show no drift. Both production builds succeed, and I clicked through the calendar, business settings, reminders and booking screens with no errors from the upgrade.
