feat: Add integration tests using patrol compatible with github actions

[andreped]

As Maestro did not work that great with GitHub Actions, we could explore Patrol as an alternative that should work better with Flutter.

Unclear if it works better for GitHub Actions though, but it remains to be seen.

Patrol sadly has the exact same issues as Maestro when running in GitHub Actions.

This seems to be an underlying problem with GitHub Actions Runners just not being powerful enough.

That is very unfortunate and that means that there is really no way to run these tests on GitHub-hosted servers.

So we likely need to self-host these jobs. That can be done though, but its unfortunate...
