fix(datatables): unbreak two operator messages and two comments that described other code

The two strings this branch added for states an operator hits once — the catalog write that
matched nothing, and the delete that stranded a pointer — were collapsed from their multi-line
form with the indentation left in, so both rendered with a fourteen-space gap mid-sentence.

`list_datatables` claimed to report a chain it cannot follow and then dropped it; it does drop
it, and the comment now says why that is the right place to stay quiet. The non-superadmin
check in `edit_datatable_config` was introduced as also covering references, which it does not
and need not: `reference` is overwritten from the stored entry for every caller before the
check runs.
