Table selection reset issue after PR #1470

### Current Behavior

After the changes introduced in [PR #1470](https://github.com/FlowFuse/node-red-dashboard/pull/1470), the table selection is automatically cleared when new data arrives.

### Expected Behavior

Users should have the option to retain their selection when new data updates the table (e. g. option in this ui-table node)

### Steps To Reproduce

1. Populate the table with dynamic data (e.g., from multiple MQTT topics).
2. Select a row.
3. When the selected vehicle sends new data, the selection is lost.

### Have you provided an initial effort estimate for this issue?

I have provided an initial effort estimate

Start by tracing the ui-table selection handling and the changes introduced by PR #1470, focusing on what happens when new data arrives. Reproduce the MQTT-style update sequence from the issue and verify that the completed work lets users retain or clear their selection through a table option.
