feat: persistency on game settings & clear button

[csantosr]

#6

Changes:

• Converted gameSettingsAtom from a regular atom to atomWithStorage for localStorage persistence
• Added hydration logic to load saved settings from storage into the form on mount
• Added a "Clear" button with translations in English and Spanish to reset settings to defaults
• Implemented auto-save functionality that persists form changes to storage as the user types
