Move common request specs into shared_examples

See merge request gitlab-org/gitlab!22428

* In preparation for the specs being reused, move them into
shared_examples.

Previously when an exception occurred in Sidekiq, Sidekiq would export
logs with timestamps (e.g. created_at, enqueued_at) in floating point
seconds, while other jobs would report in ISO 8601 format. This
inconsistency in data types would cause Elasticsearch to drop logs that
did not match the schema type (date in most cases).

This commit moves the responsibility of formatting timestamps to the
Sidekiq JSON formatter where it properly belongs. The job logger now
generates timestamps with floats, just as Sidekiq does. This ensures
that timestamps are manipulated only in one place.

Add support to import award emojis for missing entities

Added changelog entry for the fix
Corrected typo in spec description

**How?**
Making this spec a full mount instead.

**Why?**
The test was failing with an error in our
GlModal that `$refs.modal.show` was not
a function. This is because shallowMount
will stub the internal b-modal. So that we're
not messing with internals too much, let's just
do a full mount here :)

Unquarantine protected branch tests

See merge request gitlab-org/gitlab!22724

We are unquarantining this test for two reasons.
 1) Because of
https://gitlab.com/gitlab-org/gitlab/merge_requests/22525 has
not been merged yet, we cannot run this test in quarantine and we need
to run the test to determine if it is still flaky, and if it is we can
then examine the artifacts.
 2) Because we want to know if Sanad's changes have fixed this test

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.
