test: broaden the fold-parity property test to the full event surface

Extends the round-trip live-vs-replay test to ~45 event types (bots, news,
reports, help tickets, oper grants, session exceptions, vhost forbid/template,
entrymsg, noexpire, oper notes, group founder, default bot, account email).
All pass — jupes was the only divergence — so this now guards essentially
every event's live mutation against its apply() arm.
