[Bug Fix] Move ruby-ui-toaster id from turbo-frame to <ol>

turbo_stream.append('ruby-ui-toaster') was injecting toasts INSIDE
the turbo-frame wrapper but as siblings of the <ol>. The MutationObserver
in toaster_controller watches the <ol>, so new toasts were never
tracked and never animated in.

Drop the turbo-frame wrapper (refresh:morph wasn't actually wired to
flash on navigation anyway) and put the target id on the <ol> itself.
Now Turbo Stream appends land where the controller can see them.
