#9240 hears how many screens tall the held and bets phone looks are, read from the check API

Intent: the person on #9240 gets the numbers they asked for (replaces #9458).

Done:

[ ] A comment on #9240 gives screens and sideways for the phone looks of /preview-admin/sample/held and /preview-admin/sample/bets, copied from the looks field of GET /api/v1/repos/trevato/forge/commits/:oid/check for a commit on main made after the two issues this waits for landed, naming the commit and the run id. When that run's looks is empty, read them from GET …/pulls/:number/checks of the pull that put the commit on main, and name that pull.
[ ] When either is over 3 screens, the comment names the section that makes it tall.
[ ] When neither route has a looks entry for both paths, the comment says so and which route was read, and nothing else: that is a finished run, not a decline.

No code changes in this issue.
