Subject: [PATCH] fix(uakino): add HTML page fallback when playlist API returns
 no data

Handle cases where UAKino playlist requests return empty results by
resolving stream URLs directly from the content page HTML.

Add a fallback parser that extracts video sources from `link[itemprop=video]`
or `iframe#pre`, and use it to return playable movie or single-episode
responses instead of failing immediately.

Ensure Ashdi links consistently include `multivoice` for movie playback,
including episode file URLs, to improve stream compatibility.
