Refactor app version handling in appupdate.js and rpc.js

- Updated `getRunningAppVersion` to retrieve the version from `package.json`, ensuring accurate version representation.
- Modified `getAppVersion` in `rpc.js` to utilize the refactored `getRunningAppVersion`, improving consistency in version reporting.
