[Bug] Unequipped weapon class indicator colored inconsistently on donate screen (minor)

[Trotter]

In the Donate section of the purchase screen, any unequipped weapon's class is colored based on the class of the last mech inspected, rather than the classes in the entire squad (like in the Acquire section). Eg, if I open up my Prime mech and then go back to the purchase screen, my unequipped Shrapnel Cannon says Brute Class Weapon in red, even though I have a Mirror Mech in the squad. If I open/close the Mirror Mech first, the text is green.
