fix(anki): clip mined media on the sub-delay retimed timeline

mpv's sub-start/sub-end and parsed cues carry the subtitle file's own
timestamps; sub-delay (z/x, sub-step) only moves where mpv plays them.
Mining now shifts subtitle timings onto the video clock before media
generation, review, and MiscInfo timestamps.
