fix(about): decouple app version badge from tool version probes

getVersion() is a local, millisecond call but was awaited together with
loadAllToolVersions() in a single Promise.all, so setVersion and
setIsLoadingVersion only fired after all six tool checks finished. The
version badge under the app icon therefore waited for the whole batch.

Split the mount effect into two independent chains: loadAppVersion sets
the app version (and clears its loading flag) the moment getVersion()
resolves, while loadAllToolVersions runs its own progressive fan-out.
The two no longer block each other.
