Add a marketing landing hero and a live chain/round status strip

The user page's login screen was a bare test dashboard with no explanation
of how the lottery works; it now leads with a hero (3-step explainer, trust
pills) shown only while logged out, plus a bento-style nav and a glowing
round card during the draw.

Both the user and admin pages now show the current chain tip height and
lottery status (open / drawing / waiting for next round) via a small status
strip, polled from /rounds/current (extended with chain_tip_height sourced
from ElectrumListener.tip_height).
