Table grid with flags

Starts a local server with a table containing an index column and a boolean flag column. The flag column is marked with Arrow metadata so the viewer's card/grid view can toggle flags and persist them back to the server.

The flag column remains part of the table data. Its current boolean value controls the flag icon shown on each grid card. Clicking the icon immediately updates the visible table state and sends an upsert back to the server containing the row's table-index value plus the new flag value. The rerun:is_table_index column is required so the server knows which row to update.

<!-- TODO(#12745): this is still experimental -->

Enable Settings > Experimental > Table cards and blueprints in the viewer, then open the printed URL.
