Dropping a sev1-2 care nudge while you're away is right and still happens.
But it was a bare `continue`: no row, no log, so "she dropped it", "the gate
suppressed it" and "the rule never fired" all looked identical afterwards.
Adds a 'dropped' delivery status (migration #12 widens the CHECK constraint;
sqlite can't do that in place, so the table is rebuilt) and records the drop
as one delivery_attempts row plus a log line.
No nudges row for a drop: that table feeds the ignored_rate signal, and a
nudge nobody could see must not count as ignored.
TestVoiceNoSessionFallthroughLeavesOutboxTrail expected exactly one row for
sev1-2 when voice had no session. It now expects the voice failure plus the
drop, which is the point of the change.
