doom scroll and viewer improvements

- move play/pause to clicking the video directly; remove dedicated button
- replace emoji mute icons with flat minimal SVGs
- add view-in-library button in doom scroll that navigates to the file's
  directory and opens it in the regular viewer
- add display text overlay button in doom scroll and image lightbox;
  shows extracted text (translated by default when available) in a
  semi-transparent box at the bottom; toggle between translated/original
- hide tag panel by default in image lightbox and video player modal
