clearance: act on drb-correlation-review of f0a88d4

Review of the first clearance fix found it pushes toward early resolve:
- parser cleared units on questions ("45-9, are you clear?"), negations
  ("not clear yet"), orders ("clear the scene", "clear to transport"),
  places/times ("Room 2 clear", "1400 hours, clear") and split "45 9" into
  unit 45. Now rejects "?", not/is/are/you, anything after the status word
  but sign-offs, place/time words; joins "45 9" -> "45-9".
- a clear from a unit never active on an incident was recorded in
  units_cleared and could pass the all-clear gate. Only units actually
  active there can clear there now.
- clearance-only calls skip the LLM tier (same as thin calls): only the
  rules engine's unit match can say which incident a 10-8 belongs to.
- replay incident view carries srcaddr/srcaddrs for the radio-ID clearance
  investigation.

Replay 09-22 10:00-12:00 ET with f0a88d4: real clears 0 -> 2 (both LLM
closure), unit clears still 0 — the parsed clears are right but those
units were never recorded as assigned (Whisper mangles unit IDs at
dispatch), which this commit does not fix.

c2-core: 465 pass.
