Three-trigger keyboard weapon groups: 1=lasers 2=PPCs 3=missiles (task #43)

Browse Source 
Interim pod-like grouping ahead of the authentic ConfigureMappables/
ChooseButton mapper channels (decomp-anchored in open-questions):
- Three fire channels like three pod buttons: gBTWeaponTrigger (lasers,
  key 1 or SPACE), gBTPPCTrigger (PPCs, key 2), gBTMissileTrigger
  (missiles, key 3 or CTRL). Keyboard only per user (mouse buttons
  removed).
- EmitterSimulation picks its channel by classID (PPC 3028 vs Emitter
  3016); BT_AUTOFIRE holds all three.
- The BT_BEAM_LOG sampler modulus 30 aliased to ONE weapon under the
  new synchronized 5-beam volleys (5 | 30) -> 31 (coprime).

Verified: all 5 energy weapons fire (31 samples each), aimed hits land,
kill completes.
