[Canvas] Fix flaky test failures when navigating to Canvas app (#164376)

## Summary

Closes #163303.
Closes #163368.
Closes #163903.

This fixes a rarely occurring flaky test failure while navigating to the
Canvas app where the `currentURL` check fails. The cause is
`navigateToApp` goes to `app/canvas#/` which includes a hash get
redirected by the Canvas app to `app/canvas/`, and fails when
`app/canvas/` doesn't match `app/canvas#/`. I've chosen to disable this
check when navigating to Canvas to avoid this flakiness because I
couldn't remove the hash from the URL while using `navigateToApp` or
`navigateToURL`.

Instead of checking the URLs match, I opted to check that the workpad
listing page loaded correctly.

### Risk Matrix

Delete this section if it is not applicable to this PR.

Before closing this PR, invite QA, stakeholders, and other developers to
identify risks that should be tested prior to the change/feature
release.

When forming the risk matrix, consider some of the following examples
and how they may potentially impact the change:

| Risk | Probability | Severity | Mitigation/Notes |

|---------------------------|-------------|----------|-------------------------|
| Multiple Spaces—unexpected behavior in non-default Kibana Space.
| Low | High | Integration tests will verify that all features are still
supported in non-default Kibana Space and when user switches between
spaces. |
| Multiple nodes—Elasticsearch polling might have race conditions
when multiple Kibana nodes are polling for the same tasks. | High | Low
| Tasks are idempotent, so executing them multiple times will not result
in logical error, but will degrade performance. To test for this case we
add plenty of unit tests around this logic and document manual testing
procedure. |
| Code should gracefully handle cases when feature X or plugin Y are
disabled. | Medium | High | Unit tests will verify that any feature flag
or plugin combination still results in our service operational. |
| [See more potential risk
examples](https://github.com/elastic/kibana/blob/main/RISK_MATRIX.mdx) |
