Add migration logging for gauges

[kertal]

Summary

In #34982 the migrations logger was added to the migration's transform function.
Motivation: There are several try {} catches {} in the code, to prevent the whole migration from failing. But there is lack of information, why the execution failed. Lost info for debugging in development and of course in production.

Old:

catch (e) {
   // ⛄ Let it go, the data is invalid and we'll leave it as is
}

New:

catch (e) {
   logger.warning(`Exception @ migrateGaugeVerticalSplitToAlignment! ${e}`);
   logger.warning(`Exception @ migrateGaugeVerticalSplitToAlignment! Payload: ${visStateJSON}`);
}

This PR implements this pattern in a migration introduced in #34845, since there are several old patters, it could be applied to other migration, or of course future migration code

LGTM, but there are sooooo many unrelated changes, and I just want to say that I noticed :))

thx @spalger, yes better do unrelated formatting changes in different PRs .. in this case I'm still researching which of my fingers triggered the unintended auto formatting ... so far, my left thumb denies that he was involved :)
