fix, use ovm.change.uuid in cli and api-server (#2793)

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> Standardizes log field key for change UUID to `ovm.change.uuid` in API
server and CLI change commands.
>
> - **Logging**:
>   - Standardize change UUID field to `ovm.change.uuid`.
> - API Server (`api-server/server/changesservice.go`): update log
fields in start/end change flows and related messages.
>   - CLI:
> - `cli/cmd/changes_get_change.go`: log "found change" with
`ovm.change.uuid`.
> - `cli/cmd/changes_list_changes.go`: use `ovm.change.uuid` in info
logs and error field contexts for related snapshot/bookmark fetches.
