Subject: [PATCH] refactor: split EventLog into separate components and hook up
 new Event search (#7777)

Hooks up the new Event search and filtering capabilities to the new
Event Log component. In doing so, it also splits the existing EventLog
component into two: `LegacyEventLog` and `NewEventLog`. The naming is
probably temporary, as the old EventLog isn't really legacy yet. But we
can rename them later.

The other half of #7768 .
