Media grids: one tile for a clip uploaded twice, and a picture that won't load stays outHEADmaster

- Videos: one person's clips of one size to the byte are one clip. Beatbox
  Serenade posted the same video as a note and as a video event, each
  upload a fresh Blossom hash, so neither the file nor the words matched.
  Only a size the post or the host states counts (a bitrate x duration
  guess is marked sizeGuess and never matched).
- Images: a picture whose load failed was hidden by a class the next
  repaint rewrote, so the broken-picture glyph came back (a deleted
  nostr.media file in #artstr). Failed pictures are now remembered for the
  session and left out of the grid.
- A tile fetching its own frame froze the whole tile against repaints, so
  one built for the one-to-a-row layout never got its --ar in justified rows
  (zero width). Only the player and its stand-ins are frozen now; the
  render draws the cost badge itself. Tile pictures no longer size their
  tile (a frame-grab <video>'s 320px stretched its row).
- Test fixtures that served one file under several names (or one imeta
  size for every clip) now differ per clip.
