Nicolas a55be951e3 Compare dropdown fails when selecting branch with no common merge-base (#37470) (#37472) ...

## Summary

- handle compare requests where base and head refs have no common merge
base without returning 500
- keep the compare branch selectors usable and show a clear warning
message
- add regression coverage for unrelated-history compare selection and
merge-base error detection

Fixes #37469
