app: live color swatch and a project-media eyedropper in the color picker

- the swatch now follows the draft color while the popup is open
  (cancel still reverts) and set_effect_param failures are logged
  instead of silently reverting the swatch
- the popup lists project footage thumbnails; clicking a pixel picks
  its color into the draft (contain-fit coordinate mapping, no new
  dependencies)
- i18n: ofx.color.pick_project in all eight packs
