Zap screens show the recipient, cap amounts to Spending, faster search

The zap flows (ark-direct and Lightning) show the recipient's avatar
chip instead of a bare name, and their LNURL ceiling is now capped by
our own Spending balance — when Spending can't cover their minimum the
amount field is replaced by a plain "not enough in Spending" notice
rather than an impossible "min 1 · max 0" range. The confirm path
enforces the same cap.

Recipient search feels instant now: the first short query fires after
120ms (the wait users actually notice) and longer mid-word queries wait
500ms to skip characters still being typed; cached prefixes stay
instant.

Onboarding success screen: check below the title and larger.
