Retry oversized video downloads instead of giving up permanently

VK can briefly serve a not-yet-transcoded master stream on a capped-height
URL right after a video is published, tripping the size check on the very
first attempt. Treat that as transient (retry with a longer backoff) instead
of failing permanently, and merge the fallback note into a single "Смотреть
видео в VK" link instead of two separate lines.
