HUD: per-weapon pip data dump + the real authored ranges recorded

[hud] pip diagnostic logs each registered pip's classID/PipPosition/
WeaponRange/PipExtendedRange/PipColor. The live dump corrects the
"everything is 500m" assumption: BLH lasers red @500 (x3, ext=1),
missiles amber @800 (x2), PPCs blue @900 (x2) -- the pips sit at their
weapons' max-range marks on the range ladder (caret below a pip = that
weapon reaches), so 7 weapons read as 3 weapon-system groups. KB +
comments corrected.
