Inventory UI Improvements Equipment & Quality of Life Improvements

This iteration introduces a key visual indicator to help players make faster gearing decisions and ensures this information is consistently available throughout the game.

Quality of Life & User Interface (UI)

- [x] **Visual Upgrade Indicator:** Items in the inventory that are stronger than the corresponding equipped item now display a green upgrade arrow (▲) for easy identification.

- [x] **Indicator Consistency:** The upgrade indicator is now visible in all views where the inventory is interactive (shop, forge, alchemist, etc.) and in the item details modal, not just in the combat view.

- [x] **Equip From Anywhere:** The "Equip" button is now always available in the item action modal, whether the player is in the village or in combat, streamlining equipment management.

- [x] **Equipment Comparison Tooltip:** When hovering over an equippable item in the inventory, the tooltip now displays a direct comparison against the currently equipped item. Stat differences are color-coded (green for an upgrade, red for a downgrade) to aid in quick decision-making.
