Add a branding/feature panel next to the sign-in form

The login screen was just a bare card on a dark background. Adds a
feature-highlight panel alongside it (tagline, what the app does, a
scripture quote) on wider screens, using only colors already in the
app's palette (slate-900/300/400, white, sky-500) — no new theme.
Collapses to the original single-card layout on mobile.
