Owner: plate reads should become traffic stops. Held-out replay of 09-21
(server-26#170): Ossining's Post 4 stops were read out only as plates
("Frank David Boy, 4514", "Lincoln, Charlie, Robert, 7-4-0-7") and never
became incidents.
The self-initiated backstop now treats two+ phonetic letters followed by
3-7 digits as a stop — but only when extraction found no other event in
the call (a plate on an MVA, tow or parked-car complaint stays with that
event), and never on MTA/rail/bridge/fire/EMS/DPW talkgroups.
c2-core: 475 pass.
