feat: improve test setup and authentication handling

- Added `dev:test` script to package.json for streamlined testing without file watching.
- Introduced `kill-test-servers` script to ensure no existing servers are running on test ports before executing tests.
- Enhanced Playwright configuration to use mock agent for tests, ensuring consistent API responses and disabling rate limiting.
- Updated various test files to include authentication steps and handle login screens, improving reliability and reducing flakiness in tests.
- Added `global-setup` for e2e tests to ensure proper initialization before test execution.
