* Default isAdultContentEnabled to false on all devices. The original intent of setting the default based on the device was to make the maximally-permissive choice. It turns out this was a mistake as it created sync issues between devices; users would be confused by the lack of congruity between them. We have to go with false by default to ensure sync is retained. * Update preferences model to use new sdk api * Delete dead code * Dont show the iOS adult content warning in content filtering settings if adult content is enabled * Bump @atproto/api@0.6.8 * Codebase style consistency
