The version label now renders 'v0.5.86 (<shortsha>)' when the flake build
injects NEXT_PUBLIC_GIT_SHA (git commit identity of the deployed artifact),
so any running dashboard traces to its exact source commit. Falls back to
semver-only when the env var is absent (local dev). Also fixes the profile
page repo link back to asepharyana/9router (MIBP merge target), replacing
the mhiqrambg fork label left over from the merge.
