ThemeBuilderEdits::showing() splits the live templates that show a layout
into editable ones (named under templates) and a hidden_templates count;
confirm is still decided on all of them, so a layout shown only by
uneditable templates still needs confirm. The live split is read once per
write for the confirm check and the field warnings, and field warnings now
also survive a non-confirm refusal such as the P9 backup refusal (M-12 a).
replace-text passes hidden_templates on; the write schema lists it.

With the library group disabled the entries stay unreadable and unwritable, but
page outline, node-get and render summary still name global module IDs; full
hiding follows in 3b.
