collapse 20 pass-through use cases; handlers call ports directly

delete get/list/list_by_owner channels, get_settings/activity_log admin,
get_item/get_sync_status/list_collections/list_seasons/list_shows/list_genres library,
get/list/delete providers, get/list/patch_label config_snapshots,
get_active/list_history/delete_after schedule — all single-delegation.

remove ChannelQueryDeps, LibraryQueryDeps, deleted query/command structs.
add direct port fields to AppState. update MCP crate accordingly.
