fix: last updated setting in x/marketmap keeper

[aljo242]

Closes CON-1839

• call SetLastUpdated for any Set or Remove calls in the keeper. (previously these calls were only done during the MsgServer which meant that hooks, or any keeper calls that are not part of a MsgServer call were not updating LastUpdated)
• Add more testing around the LastUpdated field. Use randomized blockheights instead of constants
• add checks to our E2E tests to ensure that the LastUpdated field is updated for all Tx we call.

Note, this fix is only for on-chain code, so a full upgrade would be needed. This is also state-breaking, so we will need to make a new v3.x release as any v1 or v2 version of the code will result in disparate states (last updated will be updated differently).

I will make another PR that will only updates the sidecar, which can be rolled out more quickly.
