Reduce logs payload by selecting visible columns

Problem
Logs queries use SELECT *, which transfers and parses more data than necessary for the table view.

Proposed change

• Select only visible columns for the logs table.
• Fetch full row data on demand when opening the detail modal.

Acceptance criteria

• Logs view loads faster on slow networks.
• Detail modal still shows all fields when opened.

I also wonder if we should defer this query until after the view is requested (t keyboard shortcut).

It should be running after the render-critical queries have completed, so that it still feels snappy when you toggle the view.
