Fixes two issues found during manual verification:
- fragments/toast.html was missing class="toast-container" on the
swapped-in element, so the container lost its fixed-position
styling after the first swap.
- htmx:oobAfterSwap's event.detail.target is the *old* element that
just got replaced (outerHTML oob-swaps detach it), so the dismiss
timer must look up the live #toast-container by id instead of
trusting that stale reference.
