Replace nodes in subnet x4jtx

Replace nodes in subnet x4jtx

Motivation: Replacing two nodes (hcojr, oqbh3) that are failing to upgrade

Decentralization Nakamoto coefficient changes for subnet x4jtx-5dnbo-v3exa-vzamo-teufh-qsiit-txx4g-mi76n-ckrfl-oc5a6-nae:

    node_provider: 3.00 -> 3.00    (+0%)
      data_center: 3.00 -> 3.00    (+0%)
data_center_owner: 3.00 -> 3.00    (+0%)
             area: 3.00 -> 3.00    (+0%)
          country: 3.00 -> 3.00    (+0%)

Mean Nakamoto comparison: 3.00 -> 3.00 (+0%)

Overall replacement impact: equal decentralization across all features
