This commit implements comprehensive timezone and time format customization:
## Backend Changes
- Added timeFormat field ('12h' | '24h') to user preferences JSONB in user entity
- Timezone field already existed in user entity, now actively used
- Backend ready to accept timezone on registration
## Frontend Components (2 new)
- TimeZoneSelector: Dropdown with timezones grouped by region (Americas, Europe, Asia, Pacific, Africa)
* Auto-detect button to detect browser timezone
* Save functionality with success/error feedback
* Integrated into Settings > Preferences section
- TimeFormatSelector: Radio buttons to choose 12h vs 24h format
* Live preview showing current time in selected format
* Save functionality with user feedback
* Integrated into Settings > Preferences section
## Timezone Auto-Detection
- Register function now auto-detects user's timezone via Intl.DateTimeFormat()
- Detected timezone sent to backend during registration
- Timezone stored in user profile for persistent preference
## Enhanced useLocalizedDate Hook
- Added useAuth integration to access user timezone and timeFormat preferences
- Installed and integrated date-fns-tz for timezone conversion
- New format() function with timezone support via useTimezone option
- New formatTime() function respecting user's 12h/24h preference
- New formatDateTime() function combining date, time, and timezone
- All formatting now respects user's:
* Language (existing: en, es, fr, pt-BR, zh-CN)
* Timezone (user-selected or auto-detected)
* Time format (12h with AM/PM or 24h)
## Settings Page Updates
- Added TimeZoneSelector to Preferences card
- Added TimeFormatSelector to Preferences card
- Visual separators (Dividers) between preference sections
- Settings now show: Language | Units | Timezone | Time Format
## Translations
- Enhanced settings.json with timezone and time format keys:
* preferences.timezone, autoDetectTimezone, timezoneUpdated
* preferences.12hour, 24hour, timeFormatUpdated
## User Experience Flow
1. User registers → timezone auto-detected and saved
2. User can change timezone in Settings > Preferences > Time Zone
3. User can change time format in Settings > Preferences > Time Format
4. All dates/times throughout app respect these preferences
5. Changes persist across sessions
