style: drop stale SwallowedException suppression on transcodeVideo

transcodeVideo logs each caught exception via .message, so Detekt's
SwallowedException never fires — only TooGenericExceptionCaught does
(NullPointerException and Exception are both on its generic-names list).
Trim the suppression to the rule that actually triggers.
