add notifications to web admin

[djanogly]

This pull request improves the notification cue system for inbox events by introducing a new, more distinctive "bing" sound, synchronizing notification preferences across tabs and components, and displaying a badge for unread inbox messages in the sidebar. It also sets sound notifications to be enabled by default and adds robust event broadcasting and listening for preference changes.

Notification sound improvements:

• Replaces the old single-tone sound with a new playInboxBingSound function that plays a two-tone "bing" sound, implemented in a new utility (playInboxBingSound.ts), and updates all relevant components to use this function instead of the previous inline implementation. [1] [2] [3] [4]

Notification preferences synchronization:

• Introduces the INBOX_CUE_PREFERENCES_UPDATED_EVENT event and a broadcastInboxCuePreferencesUpdated function to broadcast inbox cue preference changes across tabs and components, ensuring all listeners are updated immediately. Components now listen for this event in addition to the storage event. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]

Sidebar unread badge and notification cues:

• Adds an unread badge for the inbox in the sidebar for admin users, showing the count (capped at "99+"), and plays the notification sound when unread counts increase, based on user preferences. [1] [2]

Default preferences update:

• Changes the default inbox cue preferences so that sound notifications are enabled by default, and updates tests accordingly. [1] [2]

Testing improvements:

• Adds a test to ensure that broadcastInboxCuePreferencesUpdated correctly dispatches the custom event for same-tab listeners.
