Log out after the group template test

Closes #34736

See merge request gitlab-org/gitlab!19050

All QA tests expect to be able to log in at the start of the test.
That's not possible if a test leaves the browser logged in when it
finishes. Normally this isn't a problem because Capybara resets the
session after each test. But it does that in an `after` block, so when
a test, like this one, logs in in an `after(:all) block, the browser
returns to a logged in state *after* Capybara has logged it out. And
then the next test will fail.

E.g.: https://gitlab.com/gitlab-org/gitlab/issues/34736

The fix is to log out once we're done in the `after(:all)` block.

Add ability to search list of Sentry errors by title in Gitlab

See merge request gitlab-org/gitlab!18772

* Moves search bar next to the button
* Adds minimal styling

In many cases, we were only measuring the time to return from the Gitaly
RPC, not the total execution time of the RPC for streaming responses. To
handle this, we wrap the RPC in a new method,
`GitalyClient.streaming_call` that yields a response and consumes it.

Only `CommitService` has been updated to use this new measurement.
Other services should be updated in subsequent merge requests.
