feat: custom ghost icon + move Ghostgram Settings under Кошелёк

- Generated ghost icon for Ghostgram Settings menu item
- Added GhostgramSettings.imageset (@1x/@2x/@3x PNG)
- Moved Ghostgram Settings from .advanced section (between Privacy &
  Chat Settings) into .myProfile section, placing it directly after
  'Мой профиль' (visually appears just below Кошелёк in the list)
- Replaced generic Appearance icon with new custom ghost icon
