 * Tests for appPaths.ts
 *
 * NOTE: In test environment, the `electron` module is mocked in setup-vitest.ts
 * The mock provides:
 * - app.setPath(key, value): Stores path values in memory
 * - app.getPath(key): Retrieves stored path values
 *
 * This allows appPaths.ts to correctly set userData path to 'userData-test'
 * during test execution, ensuring test databases and settings are isolated
 * from development/production data.
