FS507D asset recovery, ConLobby V5.0.7Df promotion, mechlab New-Mech crash fix

FS507D_20161015 release analysis wrap-up (drop itself is gitignored; art-review
folder kept local for review):
- Recovered the only assets our tree lacked: 13 hsh HUD/radar/mech bmps and the
  two 5.07D lobby decals (decal_46/47.tga, extracted from release props.mw4 via
  a ported gos_LZDecompress).
- ResourceImagePool.cpp: missing-texture placeholder is now LAB_ONLY (editor
  keeps degraded mode); Release restores the original fatal STOP. Release +
  Profile rebuilt, 0 errors.

Console script reconciled:
- ConLobby.script.new ("BattleTech Console V5.0.7Df", newest revision anywhere)
  promoted to Content\ShellScripts\ConLobby.script; .new removed; stale loose
  deploy copy removed. Verified in-game (console title shows V5.0.7Df).
- Corrected CLAUDE.md: the release never "renamed" the console to
  ComputerPlayer.script -- the resource packer stores script contents under
  alphabetically skewed entry names (runtime resolves the same pairing).
  Packer quirks documented (stale entry carry-forward on incremental builds,
  name/content skew in directory sweeps).

Mechlab bug fix (first FireStorm bug hunt):
- New-Mech dialog showed blank rows for Wolfhound/Zeus and crashed (KERNELBASE
  read AV) when creating a Zeus. Root cause: newmech in chassis.script created
  its Type droplist without setting $$m_listBoxSize$$, so capacity defaulted to
  60 while 65 chassis were written in -- OOB script-array writes. Fixed by
  sizing the list from $$m_chassisCount$$. Latent stock-MW4 bug armed when the
  FireStorm roster passed 60 chassis. Verified: Zeus variant creates cleanly.

props.mw4 fully repacked (decals + promoted console + mechlab fix, junk
.new/.org entries gone); game deploy refreshed at MW4\. Gitignore: FS507D drop
and player-created MW4\Resource\Variants.
