feat: add push notification tracking

[iamacook]

What it solves

Adds cached tracking to push notifications

How this PR fixes it

Due to technical limitations and a desire to keep the service worker small, every notification that is shown/clicked increments a counter in a new notifications-tracking-database IndexedDB database. A tracking event is then dispatched for every count when the UI is next shown.

How to test it

1. Ensure notifications are subscribed to and trigger one when the Safe is closed.
2. Open the Safe UI and observe a tracking event, labelled correcty.

Checklist
