Fix zap hang from dead outbox relay, add note preview to zap history

Override NDK default outbox relays (purplepag.es DNS failure was stalling
getZapInfo), add 45s zap timeout, disable outbox on NWC instance, fix
follower notification dedup in poller. Zap history rows now show a
clickable preview of the original zapped note.
