Replace the subtle petal animation with a full block-found party:
confetti rain, sakura petals, ember burst, and a dismissible banner
showing block height and reward. Triggers on pool block finds (not
every network block). Animations loop until the user clicks dismiss.
Fix ZMQ stale banner false-positiving during long block intervals by
comparing ZMQ age against tip-change age instead of a fixed 30-min
threshold. Add tip_changed_age to the snapshot so the UI can tell
"no blocks on the network" from "ZMQ is broken". Use solid background
colors on health banners instead of transparent rgba.
