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)
