Nico a9e6a0f372 Fix nats_test.go flaky tests (#37976) ...

Context:
https://fleetdm.slack.com/archives/C019WG4GH0A/p1767759920870649

Looks like some of the tests in `nats_test.go` are failing due to
timeouts. The timeout used for the context in these tests is 5 seconds.
Instead of increasing it, I decided to reduce the number of logs that
are written in tests as well as some sleep statements that I don't think
are needed.
Note that in `nats.go` we use `context.WithTimeout` so that's why the
context deadline exceeded error is raised.

## Testing

Did 5 test runs and measured the test completion time

Completion time (avg): 1.23s

### After
