🎨 Palette: Add accessibility attributes to icon-only close buttons

[TargetMisser]

💡 What:
Added accessible={true}, accessibilityRole="button", accessibilityLabel={t('close')}, and a generous hitSlop to icon-only close buttons (<TouchableOpacity>) in DrawerMenu, ProfileSwitcherModal, and ShiftTimeline. Added the localized 'close' string to the translation files (src/i18n/translations.ts).

🎯 Why:
Icon-only buttons are invisible to screen readers without proper labeling. The added hitSlop also dramatically improves the touchable area of small icons on mobile devices, making them much easier to tap without increasing their visual footprint.

📸 Before/After:
Visuals remain unchanged, but the touch target is larger and screen readers will now correctly announce "Button: Close" (or the localized equivalent).

♿ Accessibility:

• Added accessibilityLabel using the t('close') translation.
• Added accessibilityRole="button" and accessible={true}.
• Added hitSlop={{ top: 8, bottom: 8, left: 8, right: 8 }} for better physical touch interaction.
