Fixed issue with mech assembly not working.

🛠️ Version 0.90 Patch Notes — Hardcore Mode Activated!
This release brings next-level realism to MechWarrior: Mercenaries—armor, ammo, and now parts management are fully integrated.

🔩 Parts Management System - If a location gets destroyed, you’ll need to source and replace the part before using the mech again. Perfect for frankenmech fans and long-form missions. This can be customized however the player wants.
Location Options:
None — No part by default; source it manually.
Standard — A basic part (no weapon slots).
Variant — Includes weapon hardpoints (same as v0.80 and earlier).

💣 Ammo & Armor is fully functional in co-op, and both systems now have customizable delivery settings.
Features:
New Operations Menu to set delivery option, cost markup, and delivery time.
Insurance payout now includes ammo market value.
Mechlab uses tabletop inventory values, scaled to MW5 values during battle based off the options set in operations.
Mechlab now allows for fractional ammo bins like MercTech V3 had. You can set your ammo bins by how many rounds you want up to 1 ton.

📊 Battle Value Display
BV now shown on the deployment screen.
Future support for BV-based mission limits (in addition to weight class) is in the pipeline.
