fix: Delete obsolete "configured*" keys from config table (#7171)

[iequidoo]

Based on #7116
Close #7171

#7116 already has migration 134, so this is better rebased on top of #7116 as @hpk42 already installed #7116 (never a good idea to test PRs with migrations on a live account, but well)

It's fine if you don't install a PR with a migration on all your devices to have a way to recover. Otherwise if two people decided to test two different PRs with migrations, there's no way to recover

But this PR here doesn't even touch ConfiguredAddr, so, I think it's fine?

We do need to keep ConfiguredAddr for now, because it's used to remember which transport is the primary transport; grepping for "ConfiguredAddr" yields 33 results.
