[Notifications] Notification Synchronization issues

Summary

The notifications indicator count updates, but the update is delayed by several seconds. You can force an update by clearing the active notification.

The highest severity of the indicator is also prone to sync issues I believe. I've seen error priority when the only notification is an info.

Expected vs Current Behavior

The notifications indicator gives timely and correct indications of notifications state.

Steps to Reproduce

1. enter this code into browser console openmct.notifications.error('test')
2. do step 1 several more times rapidly
3. Observe that the count stays static, then after a few seconds updates

• Does this impact a critical component?
• Is this just a visual bug with no functional impact?
