Magic loot -- Adds randomized magical weapon drops to the treasure system.

[Plateaus]

Adds randomized magical weapon drops to the treasure system.

• Added scalable magical weapon generation based on monster treasure level.
• Added Magic, Flaming, Freezing, and Shocking weapon traits with tiered power levels.
• Elemental weapons use the legacy LOFP proc chance and damage values.
• Magical weapon chance scales with treasure level and is capped at 35%.
• Magic power scales independently, allowing rare high-power enchantments from higher-level treasure.
• Magical traits are preserved when dropped items are picked up or removed from containers.
• Identify now applies the appropriate visible adjective to magical items and reports discovered enchantments.
• Identify explicitly reports when an item has no magical enchantments.
• Added magical-aura messaging when an enchanted weapon drops.
• Corrected elemental adjective mappings to use existing LOFP adjectives (burning, icy, and electric).
• Removed temporary 100% enchantment chance used during testing.
• Fixed chest item selection so gems are reachable in the random loot table.
