fix(admin): bulk delete swaps the episode list — Play → Download without reload

The bulk 'Delete selected files' button posted with hx-swap='none',
which makes htmx DISCARD the response — and the response is the
refreshed episode list partial. Rows (Play → Download, badges) stayed
stale until a manual refresh. Target the swap at #episode-list /
outerHTML like the Download All button; the afterSwap listeners then
reapply the (now-empty) selection and any active filter.
