Fix transcoded video playback in lightbox and slideshow

The HEVC-to-H.264 transcode kept the original file as a hidden
(non-admin) entry with transcoded_to set, but the lightbox <video>
element and the slideshow always pointed at the original file's URL.
Opening a transcoded video (e.g. via a direct ?photo= link) tried to
play the unsupported original codec instead of the browser-compatible
copy.

- album.erb/album.js: lightbox video now plays the transcoded file
  when present, while the "Download Original" link still serves the
  true original.
- all_media_entries: slideshow skips transcoded originals entirely
  since it has no separate download path.
