🎨 Palette: Add accessibility labels to close buttons

[TargetMisser]

💡 What: Added accessible={true}, accessibilityRole="button", and accessibilityLabel={t('close')} to the TouchableOpacity components used for close buttons in DrawerMenu.tsx and ShiftTimeline.tsx. Also added the new close translation string to src/i18n/translations.ts.

🎯 Why: Icon-only buttons without an accessible label are invisible or incorrectly read by screen readers. By adding an accessibilityLabel and the button role, users relying on assistive technologies can now understand the purpose of these close buttons, making the app more accessible.

📸 Before/After: Not applicable (non-visual change).

♿ Accessibility: Improved screen reader support for closing the drawer menu and the shift timeline modals by providing meaningful text ('Chiudi' or 'Close') instead of an unlabelled view.
