Fix pausing of event streams in Console

[kschiffer]

Summary

This PR changes the logic of event pausing to pause event ingestion on store level rather than component level. This means that the Console will not save up events that arrived during the pause anymore.

Closes #3324

Changes

• Extend store logic to allow for pausing ingestion of new events when the stream is paused
• Remove shouldUpdate type logic for the event component
• Add respective synthetic events for pausing and resuming the event stream
• Update event containers to pass down new action dispatches and selected pause prop
• Adjust the styling of the pause button a bit to make the paused state more noticeable

Testing

Manual testing.

Regressions

This might cause issues wrt correct event display during paused and resumed state

Notes for Reviewers

This will not interrupt the stream connection itself but only interrupt the adding of new events to the store. The event connection needs to persist e.g. in order to detect heartbeat events for end devices.
