Boss Rewards and Inventory Navigation Refined

World Boss rewards now follow the actual encounter level, while Battle targets and Inventory categories remain clearer between activities.

What changed

New World Boss Trinkets derive their requirement and stat budget from the spawned encounter level instead of the shared monster template level.
Battle remembers the last selected normal monster after a World Boss ends, and the Actions panel keeps that previous target repeatable.
World Boss chat and panels use cleaner copy without redundant click or permanence instructions.
Inventory now separates Weapons, Shields, Helms and Potions into responsive tabs, with clearer equipment requirement labels.
Cooking is presented as Alchemy, with existing consumable progression preserved and all crafted effects reorganized as Potions.
