fix: quiver replacement logic and shield-weapon equip handling

[dudantas]

• Added logic to replace an existing quiver when equipping a new one, ensuring proper unequip and feedback to the player. • Refactored shield equip logic to properly handle scenarios where a two-handed weapon is equipped in the left slot, preventing unnecessary unequips. • Improved equip flow to ensure consistent behavior for different weapon and item types, avoiding conflicts between equipped items.
