Prepare production branch: remove test files and add Dockerfile

- Remove all test files (__tests__, *.test.*, *.spec.*)
- Remove Jest configuration files (jest.config.js, jest.setup.js)
- Remove test-related scripts from package.json
- Remove Jest dependencies from package.json
- Add production Dockerfile for standalone Next.js app
- Update tsconfig.json exclusions
