Test voice fallthrough and delivery durability

Fallthrough is checked per severity through the outbox trail, so sev3/sev4
reroute and sev1/sev2 still drop. Durability uses a real store on a temp file:
a crash between Begin and Complete becomes unknown, is not resent, is not
dropped, and a late Complete cannot overwrite it. One skipped test marks a real
gap: a panic mid-send leaves a permanent pending row.
