Add root playwright.config.ts to fix test discovery

- Create root-level playwright config that properly scopes test discovery
- Configure testMatch to only find *.spec.ts files (not unit tests)
- Point testDir to ./e2e explicitly
- Fix webServer command to generate Prisma and start Next.js dev server
- Resolves test discovery picking up Vitest unit tests causing import errors
