Runtime configuration of SCT divergence checks in web extension

[hdevalence]

When using 6.0.0 from the Chrome store, I cannot make any transactions because of a sync bug causing an SCT divergence:

Error: [unknown] Tendermint error 1: failed to deliver transaction: check_stateful failed: provided anchor 602a5492caad089c2443c8e264ce87b08a652979f5e93d944293f4adb08a6908 is not a valid SCT root

I cannot debug this because there's no way to enable the SCT divergence checks at runtime. To fix this, there should be a field I can manually set in the storage inspector that configures whether SCT divergence checks are enabled. We don't need a UI for this, other than the Chrome devtools, but in the future, if someone else has an SCT divergence, there should be a way for them to produce the divergence height without having to reinstall the software.
