refactor: reorganize Config.java with grouped sections and consistent formatting

Grouped into 8 sections: General/CrossDimension/Teleport/Durability/FoodCost/Effects/RecipeToggles/RecipeOverrides

Unified TOML keys to hierarchical dotted naming (durability.basic, foodCost.basic.foodLevel, etc.)

Standardized comment style and added format example comments
