Add right-click context menu to view full record in modal

Right-click a data row shows a custom menu; choosing 'view full record'
opens a Modal displaying all fields (incl. hidden columns) fully wrapped,
so long-content fields are completely visible. Inline table keeps ellipsis.

Also fixes a pre-existing setState-in-effect lint error in
ColumnSettingsModal (render-phase reset) that would fail next build under
eslint-plugin-react-hooks v7.
