Beams at the models' NATURAL width, per-weapon tube models (de-cartooned)

Browse Source 
The "cartoonish" beams: the port drew the ermlaser tube INFLATED -- a 3.0x
glow + 0.9x core two-layer hack, 13x the authored radius.  Parsed the beam
models: ERMLASER/MLASER 0.22u radius, SLASER 0.11, LLASER 0.32, PPC 0.62 --
thin pencil beams with an authored per-class size progression; the PPC bolt
is genuinely ~3x fatter with its own 62-vert shape.

Now: ONE draw per beam at natural model scale (width multiplier 1.0), using
the weapon's OWN tube model (ermlaser for lasers, ppc.bgf for PPCs; the
s/m/llaser tubes load for other mechs' loadouts).  BTPushBeamKind carries the
model selector; BTPushBeam keeps its signature (kind 0).  Tint = 40+215x the
authored PipColor; the thin natural tubes stay under additive saturation so
the scrolling grit reads without a hand-dimmed core layer.
