fix(ci): reduce channelProfile.js size and bound relay concurrency

- Refactored `js/channelProfile.js` to use `pMapSettled` from `js/utils/asyncUtils.js`, fixing both the concurrency issue (P1) and the file size lint failure.
- `pMapSettled` replaces a bulky inline `pMap` wrapper, reducing code volume.
- Ensures `js/channelProfile.js` stays within its grandfathered line count limit (5579 lines).
