fix(test): polyfill synchronous requestIdleCallback for unit tests

Browse Source 
Fixes flaky/failing unit tests in `tests/state/profile-cache.test.mjs` caused by the recent optimization to defer `localStorage` writes using `requestIdleCallback`.

In the JSDOM environment, `requestIdleCallback` was missing, causing a fallback to `setTimeout`, which introduced asynchronous behavior that the existing tests did not account for.

This change adds a synchronous polyfill for `requestIdleCallback` in `tests/test-helpers/setup-localstorage.mjs`, ensuring that deferred writes happen immediately during testing, restoring deterministic behavior.
