fix(home): stop Next Up repeating Continue Watching

Jellyfin's /Shows/NextUp defaults EnableResumable=true, which returns a
partially-watched episode as its own series' next up — precisely the
episode /Items/Resume already returns. Home's "Next Episode" row and the
TV landing's Next Up row therefore duplicated Continue Watching card for
card.

build_next_up_endpoint now sends EnableResumable=false, and because
servers predating that parameter ignore it, filterInProgressNextUpItems
also drops any next-up entry whose id appears in the resume list. It is
the mirror of DR-089 and sits beside it: presentation-layer de-duplication
over two lists the frontend already holds. The resume filter still reads
its frontier from the unfiltered Next Up list, so pruning in-progress
entries cannot resurrect a stale resume card.

The code changes were swept into 5e8efa25 by a concurrent `git add -A`;
this carries the remainder — DR-197 / JA-036 / UT-190..192, the
renumbering off the DR-196 collision that commit created, the regenerated
matrix, and the requirement-count guard.
