x0r Shared FIA

Private Test build for RubberBandRussians on [x0r] Worthy Islands. Preserves the native Conflict BUILDING-mode vehicle-depot correction and exact faction-safe FIA sharing. Retains the 413 runtime-created Russia purchase entries and structural arsenal items with strong Enfusion element references through the deferred authoritative catalog merge. This permits the already frozen v1.0.47 replacement logic to repair only metadata-empty indexed objects while retaining valid authored entries and avoiding duplicate keys. Readiness requires all 413 intended entries while retaining the accepted native Russia weapon/equipment surfaces. Preserves the aligned x0r loading animation, modern default kits, player-created GRS loadout slots, 128 slots, NATO/Russia-only playable factions, balanced mounted vehicles, 300/400/475 MOB policies, supply, victory, rank, and quarantine policies. Not approved for public or live use until isolated runtime and client acceptance pass.
