[Feature request] LiveView check for invalid certificate counter

[sunapi386]

Describe
LiveView should check the certificate counter.

If the OnDisk counter differs from the OnChain counter by more than 1, the certificate will be invalid.

The purpose is to guard against this scenario IntersectMBO/cardano-node#4114

We will take the suggested change into consideration for an upcoming release.

Just a note - we would not want to rely on CLI or storage - but look at runtime (in line with all metrics gLV shows), we already had an item to use Koios query layer to check for latest OpCert metrics for given pool which would be refreshed at:

• KES time interval change;
• Startup of gLiveView;
• PID change of node

Also, we would need to note that KOIOS_MODE being set to N (or test_koios failing) will disable this check, the test_koios should only be called once at gLiveView startup. Worth noting that CNTools users (who allow connection to koios) already had this check , as it was taken care of with node version update as well.

This is in line with Catalyst proposal from Koios to further integrate between query layer and SPO tools
