fix(13-11): a films search found nothing — owned and peer content had no caller

Reported on-device: searching for films in AIUI returns nothing. Init only ever
asked for scope 'own' (content.list-mine — this node's own shared files), so
IndeeHub and everything else purchased, which lives in 'owned'
(content.owned-list), and other nodes' catalogs in 'peers' were never fetched.
Both scopes existed only as type-signature options with no call site anywhere
in the app.

requestArchyAllContent() now loads all three concurrently and merges once.
Merged rather than three setArchyContent calls because that sink REPLACES
films/podcasts — separate pushes would leave only whichever resolved last, the
same class of bug as the shared sequence guard fixed in aac81503. Deduped by
id, since a title can legitimately appear both owned locally and offered by a
peer. Each scope is caught individually so one dead or slow peer costs only its
own results, which is normal rather than exceptional.

requestArchyContent also stops clobbering songs with an empty array, mirroring
what requestArchyLibrary already did for films/podcasts.

vue-tsc clean, 3/3 useArchy tests pass, and the change is verified present in
the built bundle rather than assumed.
