Recipe hashing

[MaksyKun]

Some reworking regarding the recipe gui. It was continously updated and caused many lags in past.
This approach uses hashing to stop the gui from reloading when not required.

Pull Request Overview

This PR optimizes the recipe GUI by hashing and caching player state to avoid unnecessary redraws, and centralizes event routing.

• Introduces InventoryFingerprint, IngredientFingerprint, and RecipeCacheKey to fingerprint inventory, ingredients, and build cache keys
• Refactors RecipeGui.reloadRecipes to early‐exit when inventory/level/money/page/queue state is unchanged and reuses cached CalculatedRecipe
• Adds RecipeGuiEventRouter and enhances ProfessionGuiRegistry to manage the active recipe GUIs in a single registry

• [nitpick] Changing the cache key to include category.getName() may break existing persisted queue lookups for callers expecting only the profession key. Verify downstream code to ensure compatibility or migrate existing entries.

            cachedQueues.put(profession + "." + category.getName(), new CraftingQueue(getPlayer(), profession, category));

I will still put that one on draft for now due to the problem of crafting times being bypassed/skipped on relogging
