Zaps: tap again while one flies, hold the bolt to change the amount.

A pending zap no longer refuses the next tap: the optimistic tally keeps one
entry per zap and matches each report and receipt to the oldest it can
describe, so two default-amount zaps stack, settle and hand over to their
receipts one at a time. Instant post zaps run off the send screen's zap slot,
so a second tap can't evict the one still resolving, and send action ids are
unique within a millisecond.

Holding ⚡ (500ms) opens the amount screen in an edit mode — Save alone, or
Save and zap this note — from the action bar and the chat chips alike; the
press's timer lives on the element so a background repaint mid-press can't
turn a lifted finger into a hold.
