Improve Threat Monitoring backend integration

See merge request gitlab-org/gitlab!22778

Part of [WAF statistics reporting][1].

This improves the integration with the backend for WAF statistics
reporting in a few ways.

In particular, this:

- Handles 404 responses from the WAF statistics endpoint not as errors,
  but as an indication that there is no data to display.
- Displays a new empty state when there is no data to display.
- Handles 204 No Content responses from the WAF statisics endpoint, and
  continues to poll until a 200 OK response (or any error) is received.
  To do this, the existing `pollUntilComplete` utility was moved to
  a more shared location, and tests were added for it.

Disable rugged auto-detect when Puma threads>1

See merge request gitlab-org/gitlab!22328

If Puma is in use and Puma threads is more than 1, it is expected to
have performance lose by using Rugged patches, because of Rugged calls
does not release Ruby GVL while doing IO. So in this case, we will
ignore rugged automatic detect `can_use_disk?`.

Refactor `readmeFile`

Closes #121727

See merge request gitlab-org/gitlab!22243

These both ended in .yaml, not .yml, and so weren't picked up by the
changelog generator.

https://gitlab.com/gitlab-org/gitlab/merge_requests/18126

This job checks that files in the unreleased changelogs directories have
the correct .yml extension. It ignores the .gitkeep files already there.

As yamllint errors when a path doesn't exist, we have to make sure to
only add ee/changelogs when ee/ exists. (i.e. we're not adding this
check in the FOSS version.)

Ensure that instance statistics links are only displayed if a user has access to the features

See merge request gitlab-org/gitlab!22476

By asserting that the epic title is the same of the issue that
was promoted we are already testing that issue promotion works, so
better to remove this extra assertions that might cause test flaki-
ness since sometimes automatic discussions take longer to render.

Also, by removing an extra step + assertion, we make the test a bit
faster.

Finally, this way the code gets a bit shorter.

In getFileData, getRawFileData actions, and SET_FILE_RAW_DATA mutation,
ignore the early returns for when a file is deleted and readded. This
fixes issues with incorrect diff appearing because raw data wasn't
loaded correctly for deleted and readded files.

It can take longer than expected for elasticsearch to be ready to index

than only accepting a query.
