Make every settings page reachable from the launcher

Settings had a search index and the launcher had script commands, and
neither knew about the other: finding a setting meant opening Settings
first and searching there. One command per page is now generated from
the same sources the in-app search reads -- the sidebar page list, the
group routing, and the schema labels -- so a setting searchable inside
Settings is searchable from the launcher without a second list to
maintain.

Generating it surfaced a gap in the in-app search as well. Six pages had
no vocabulary at all, because their contents come from the system rather
than our schema, so searching "volume" found nothing in Settings either.
They now carry entries, which improves both surfaces.

The product prefix is dropped from every hand-written command title. The
generated ones are qualified "Settings: <page>" instead: a bare page
label collides with the feature of the same name, and two commands
sharing a title are indistinguishable in a launcher.
