fix: restore avatar rendering and split presence dot into separate button

The previous version wrapped UserAvatar in a div inside SidebarAvatar,
which broke the folds Avatar CSS (expects AvatarImage/AvatarFallback as
direct child) — causing the white circle instead of the avatar.

New approach:
- SidebarAvatar has only UserAvatar as its direct child (restored)
- Clicking the avatar opens Settings directly (original behavior)
- PresencePicker renders a small absolutely-positioned button in the
  bottom-right corner of SidebarItem (which already has position:relative)
- Clicking the presence dot opens the status picker menu
