Add canvas zoom in/out for the image previews

- New bottom-left zoom control (-, percentage, +) scales the rendered
  OG/Thumb image cards from 25% to 200% in 25% steps — only the images
  resize, not the surrounding toolbar/panel controls
- Fixed a real overflow bug this surfaced: centering flex content wider
  than its scroll container clips the left-side overflow with no way to
  reach it via scroll in most browsers. Above 100% zoom the row switches
  from center- to start-aligned so the full width stays reachable via
  horizontal scroll

Also resolves a leftover git-stash merge-conflict in the local dev
launch.json (og-generator and www configs had collided into one entry).
