feat(weapon): open chest and improve weapon damage

[olivierperez]

🚀 Feature Request

Show the buff items from the chest

📝 Describe the solution

• After an island has been completed, and before opening the interactive map
• Open the chest and see the buff items which were stored in the chest
• When an item has been picked, select the weapon to improve with it
• Then open the interactive map

🤔 Describe alternatives you've considered

• Opening the chest after navigating through the interactive map: but it would mean to have this feature and the weapon selection back to back.
