KB sweep: retire the three claims that WERE the scoring bugs

Night 13 turned up three confident KB/source notes that each closed off a
working path, and each one was the defect:

  1. context/combat-damage.md -- "@0x4c0200 is in NO table entry: dead code",
     used to justify retiring per-hit inflicted credit in build 787.  It is
     reached through BTPlayer's Dispatch override (vtable @00513300 slot 3).
     (corrected in 2772175)
  2. context/decomp-reference.md -- "shipped content authors NO role keys, so
     the cost is 0 in the field".  Wrong on both halves: the fields come from
     the role MODEL's GameModel record, not notation keys, and dfltrole
     authors killBonus=500 / deathPenalty=500 / dmgInf=1 -- the manual's chart
     verbatim.  The cost read 0 because the role was never bound.
  3. docs/RECONCILE.md -- "role registry has no WinTesla analog -> stubbed;
     base-set scenarioRole stands".  The base ctor sets it NULL, so nothing
     stood, and Mission::GetScenarioRole IS the analog.

Common shape worth remembering: all three asserted an absence (dead code, no
authored data, no analog) and none was re-tested against the binary before
being built on.  An absence claim in this KB should carry the check that
established it.
