fix(dashboard): keep the v prefix on the reported platform version

The console config ConfigMap stripped the leading v (trimPrefix "v") while
the operator's COZYSTACK_VERSION and the vX.Y.Z release tags keep it, so the
dashboard displayed 1.4.0 where the operator reported v1.4.0. Keep the tag
verbatim, and build the baked VITE_APP_VERSION fallback as v$(COZYSTACK_
VERSION) too so the deploy-time and build-time version strings stay
consistent with each other and with the operator.
