Fixed measurement unit not persisting across page refreshes:
- Settings page now includes measurementUnit in the preferences object when saving
- MeasurementUnitSelector now accepts value/onChange props for controlled usage
- Settings state properly loads and saves measurementUnit from user preferences
- UnitInput component will now correctly read imperial/metric from user.preferences.measurementUnit
Previously, measurementUnit was only saved to localStorage but not synced to backend,
causing UnitInput to always default to metric since it reads from user.preferences.

Fixed React hydration warnings caused by invalid HTML nesting in the
DeviceTrustManagement component.
## Issues Fixed
- Error: "<p> cannot be a descendant of <p>"
- Error: "<div> cannot be a descendant of <p>"
- Error: "<p> cannot contain a nested <p>"
- Error: "<p> cannot contain a nested <div>"
## Root Cause
The ListItemText component renders its secondary prop as a <p> tag by default.
We were incorrectly nesting Box (<div>) and Typography (<p>) components inside
the secondary prop, causing invalid HTML structure.
## Solution
- Removed nested Box and Typography components from ListItemText props
- Used simple text content with <br /> for line breaks in secondary text
- Moved chips (Current, Trusted/Untrusted) outside of ListItemText
- Positioned chips as separate Box between ListItemText and ListItemSecondaryAction
- Maintained visual layout while fixing HTML structure
## Changes
- primary: Now just plain text (device.platform)
- secondary: Plain text with <br /> separator instead of nested Typography
- Chips: Moved to separate Box with flex layout
This ensures proper HTML semantics and eliminates hydration errors.

Simplified the settings page by consolidating all save buttons into one
global "Save Preferences" button at the bottom of the page.
## Changes Made
### Unified Save Handler
- Merged `handleSaveProfile` and `handleSavePreferences` into single `handleSaveAll` function
- Single save handler now updates:
* Profile name

* Notification preferences
- One API call to save all settings at once
### Removed Individual Save Buttons

- Removed "Save Preferences" button from Preferences section
- Removed "Save Notification Settings" button from Notifications section
### Added Global Save Button
- Centered "Save Preferences" button at bottom of settings
- Positioned above Account Actions (Logout) section
- Large, prominent button (minWidth: 200px)
- Single source of truth for all settings changes
### User Experience Benefits
- **Simpler**: One clear action to save all changes
- **Fewer clicks**: No need to save each section separately
- **Clear feedback**: Single success/error message for all updates
- **Better UX**: Users can make multiple changes and save once
- **Consistent**: All settings treated as unified preferences
Files changed: 1 file (settings page)

## 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

* 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)

- Added detailed completion markers for each subsection
**Technical Details:**
- No migration needed - using existing preferences JSONB column
- Preferences object now includes: notifications, emailUpdates, darkMode, measurementUnit
- Endpoint: PATCH /api/v1/auth/profile accepts optional preferences object
- Validation ensures measurementUnit is either 'metric' or 'imperial'
**Next Steps:**
