refactor: Consolidate settings page save buttons for better UX

Improved the settings page by removing individual save buttons from each
preference component and adding unified save buttons per section:

## Changes Made

### Component Updates
- **TimeZoneSelector**: Converted to controlled component with value/onChange props
  * Removed internal state management and save button
  * Removed success/error alerts (now handled by parent)
  * Added auto-detect as simple button without save

- **TimeFormatSelector**: Converted to controlled component with value/onChange props
  * Removed internal state management and save button
  * Removed success/error alerts (now handled by parent)
  * Simplified to just radio buttons with preview

### Settings Page Improvements
- Added timezone and timeFormat to local state
- Created separate save handlers:
  * `handleSaveProfile` - for name/email changes
  * `handleSavePreferences` - for timezone and time format
- Three clear sections with dedicated save buttons:
  1. **Profile Information** → "Save Profile" button
  2. **Preferences** (Language, Units, Timezone, Time Format) → "Save Preferences" button
  3. **Notifications** → "Save Notification Settings" button

### User Experience Benefits
- Clearer separation between different types of settings
- Single save action per logical section instead of multiple buttons
- Consistent save pattern across all settings cards
- Reduced visual clutter with fewer buttons on page
- Better organization: related settings grouped with one save action

Files changed: 3 files (TimeZoneSelector, TimeFormatSelector, settings page)

## Notes
### Translation Best Practices
1. Use namespaces to organize translations
2. Use interpolation for dynamic values: `t('welcome', { name })`
3. Use pluralization: `t('items', { count })`
4. Keep keys descriptive: `auth.login.emailLabel` not `auth.e1`
5. Avoid concatenation, use complete sentences
### Unit Conversion Strategy
- **Storage**: Always store in metric (ml, kg, cm) in database
- **Display**: Convert to user's preferred unit for display
- **Input**: Accept user's preferred unit, convert to metric before API call
- **Consistency**: Ensure all measurements use the same preference
### Performance Considerations
- Lazy load translation files per namespace
- Cache translations in browser
- Preload critical translations (common, errors)
### Future Enhancements
- Add more languages (Arabic, German, Hindi, etc.)
- Add more units (temperature: °C/°F)
- Add regional date formats (MM/DD vs DD/MM)
- Add time format preferences (12h vs 24h)
