cdr: store Cdr events, aggregate calls, fixtures from real calls

services/cdr.ts stores every AMI Cdr event in cdr and, 5 s after a
call's last event, builds its calls row (direction, status, from, to,
DID, answered by, talk time) and call_extensions (caller, rang,
answered) per 04 §5.4; linkedids without a calls row are caught up on
AMI connect. Aggregation is idempotent.

test/asterisk/cdr-record.ts records 8 scenarios with our config, the
fake voip.ms (now shared in provider.ts) and baresip phones; each has a
fixture and a test with the expected calls row. Queue abandon and park
come with M8.

Found while recording: Asterisk 24's Cdr event has no LinkedID unless
cdr_manager maps it, its times carry no zone (now usegmtime), and the
mappings read CDR variables, so the dialplan sets CDR(SP_DID) and
CDR(SP_DIRECTION) next to the channel variables. The Asterisk image
needs a rebuild for the cdr_manager.conf change.

Task: M7-T1
