update stale media ownership language across all docs

arr_sync.sh bidirectional union replaced the old split-ownership model.
Old: HOST1 owns Movies/TV/Music, HOST2 owns Anime — each arr manages
different shares to avoid conflicts.
New: arr_sync.sh keeps all arr databases in union. Either server can
download to any share at any time. The union is the source of truth.

Auth stack references left intact — HOST1 still owns auth config
(one-way sync to HOST2). Only media library ownership language updated.
