fix: audit fixes — treatment sync, avatar upload, code consistency

- Always sync treatment end (not just early stop), pass start/end times
- treatment-done uses api.syncTreatment instead of raw http.post
- Move getApp() from module level to onLoad in treatment-done
- Avatar upload only returns URL, no longer updates profile directly
- COS CDN domain configurable via COS_CDN_DOMAIN env var
- Fix operator precedence in request.js token expiry check
- Remove unused result variable from COS putObject
