Subject: [PATCH 3/4] Fix CI build failures: proper race condition fix and
 linebreak-style for kyfromabove

- modules/services/kyfromabove.js: Fix require-atomic-updates by capturing
  a local const cache = _kyCache snapshot before the await, so all
  post-await writes go to the correct cache object. Removes the eslint-disable
  comment that was silencing a real race condition.

- modules/ui/ky_oblique_viewer.js: Fix linebreak-style error (CRLF -> LF),
  align indentation to 2-space (repo standard), convert updateImage() from
  async/await to a promise chain to resolve require-atomic-updates on _loading,
  make setAngle() synchronous (fixes require-await), and remove the redundant
  first RGB copy loop.

- package-lock.json: Regenerate to resolve merge conflict with develop branch.
