fix: use setItem helper and safer Playwright selector in tests

- Replace direct localStorage.setItem() with setItem helper in use-settings-migration.ts (line 472) for consistent storage-availability checks and error handling
- Replace brittle attribute selector with Playwright's getByRole in open-existing-project.spec.ts (line 162) to handle names containing special characters
