feat: zap renderings embed the zapped post, like reactions and reposts do

RenderLnZap, RenderNutzap, and RenderOnchainZap now show the post the zap
targets above the transfer card (via the zap note's replyTo, mirroring
RenderReaction), so the target is visible wherever a zap renders — the
thread master view, composer reply previews, and quoted embeds. Reactions
already embedded their target.
