Zaps: the sound, the sender, and one action bar for every post.

Tap feedback: a bolt strike, the amount popping off the button, the post
trembling, and the zap.mp3 clip. The clip is 62KB of base64 and messages.js
is boot code, so it is its own chunk, fetched once a zappable post is on
screen and played inside the tap once loaded; the standalone build inlines
it. Ark zap receipts are signed by the wallet key, which has no profile: they
now carry the login identity as the sender (NIP-57's P tag), readers prefer
it, and our own older receipts read as us. The action bar is the same six
slots on every post: the zap button and the who-reacted chevron are always
there (inert until they have something to do), so the first zap no longer
reflows the row, and you can zap your own posts and messages. Community
rows centre their unread dot off the edge. Also in here: reactions with
custom emoji, reply-composer focus under the tapped post, profile fetch
retry, and Lightning zap failures that say so.
