In code that hasn't changed since last review

Avoid duplicate fetch-owner events during account initialization

ui/​src/​views/​compute/​wizard/​OwnershipSelection.vue:227

handleSelectedAccountId already calls emitChangeEvent() at line 247, so invoking it here and then emitting again on line 227 produces two fetch-owner events whenever accounts are loaded. Consumers such as AssignInstance react by calling fetchNetworks(), resulting in duplicate network-list requests during initialization; emit only once for this path.
