wait-for-checks - Rewrite for reliability

[fregante]

• Closes wait-for-checks is missing or it does not merge the PR #6914

I hate this feature, it's important and it's complex. If I don't fix it this time I'll drop it.

• UI changes
  • checkbox must be updated depending on
    • the status of CI
    • visibility of merge box
• Merging
  • merge box must be dimmed when user presses "merge" and
    • checkbox is present and checked
  • merge box must be dimmed until
    • new commit comes in
    • CI passes
    • CI fails
    • user presses cancel
  • merging can proceed when
    • CI passes

I think this can be simplified a bit by matching the behavior or GitHub's auto-merge, which doesn't care about new commits or failing CI. It will just merge the PR when checks pass.

• Edit: Done 🚀

Without high-level helpers from framework, this produces a bit of spaghetti.
