- useLetterPreferences: simplify to just expose raw saved prefs + isThemeDefault flag,
no longer conflates theme stationery with saved stationery
- LetterPreferencesSection: always pull from useThemeStationery directly when
isThemeDefault, persist only on explicit user picks (handleSetStationery),
sync preview live when theme changes
- ComposeLetterSheet: same pattern — init from themeStationery, switch to saved
pref once settings load, track explicit user picks to avoid theme override
- LetterEditor drawer: remove bg-background / rounded-b-3xl / border-b card shape
