re: runtime DATA SHEET reads the live weapon record (Route B, first capture)

Drove the retail game headless (Canary + lavapipe, vgamepad) to the Ready Room
Arsenal and read the Gallery-Mode DATA SHEET for every weapon the 5%-progress
save reveals.

Two UI->field mappings are CONFIRMED against weapons whose values ARE on disc:
  Ammo Capacity  == LoadingCount      (9/9 exact matches)
  Max. Lock Ons  == TriggerShotCount  (FALCON 9AM 12 == wep_02; BUZZARD 22 == wep_04)

That makes the panel an oracle for fields the disc leaves defaulted, and it is
shown for undeveloped weapons too, so no points need spending. Recovered
TriggerShotCount for wep_05 and wep_60 (both 4, on-disc absent), and bracketed
the defaulted Power / MaximumRange via the Range/Damage letter classes.

Ruled out first: the defaults are not in hidden/DefTables.pak (no WEAPON-schema
objects there) nor in the localized GP_MAIN_GAME_* duplicates.

Also adds the two analysis examples that produce the shopping list of defaulted
fields, the screenshot harness used to drive the menus, and the evidence PNGs.
