Flakey test investigation

[jonathanKingston]

Asana Task/Github Issue:

Description

Fixes a flaky favicon + monitor (many updates) integration test. The test previously asserted an exact number of faviconFound messages at an intermediate time, which was unreliable due to the feature's debounce logic and rapid updates under a mocked clock. This change updates the test to fast-forward the mocked clock past all updates and debounces, then asserts on the first and final faviconFound payloads to ensure deterministic validation of the initial and eventual states.

Testing Steps

• Run npx playwright test injected/integration-test/favicon.spec.js
