The previous flicker fix gated the whole settings form behind a 'loaded' spinner,
which read as a small lag when opening Settings (it waited for DataStore's first
emit even though it's already warm). Instead, expose the applied theme id
(NsColors.themeId, set in applyNsTheme) and seed the ViewModel's initial state with
it, so the theme picker no longer jumps from the default — no gate, no spinner, no
delay. Remaining text fields fill within a frame from the warm DataStore.
