[dagit] Flip hideNonMatches default
Relates to #3688.
In the Run log viewer, hideNonMatches currently defaults to false, so non-matching rows will appear in context alongside filter-matching rows.
I'm going to flip this default to true instead, as it seems like it might be a point of confusion that filtering doesn't always clearly surface results.
The UI is otherwise unchanged.
Test Plan: View Run, do some filtering. Verify that the "Hide non-matches" box is unchecked by default. Check it, verify that non-matching logs are shown and that the URL updates accordingly.
