Update profile details

Would be nice to have a settings icon on the authenticated user's profile screen (`AuthProfileScreen`) that opens a modal screen with a form of sorts that allows you to update settings in your profile such as:

* Profile Image (select from the photo library + take photo (if that's not too complicated) - _we can have a separate ticket for this because I'm not sure if the API makes this easy)_
* Name
* Email
* Website

We may also want to allow updating of the following:

* Bio
* Company
* Toronto

But we can do this as part of a separate ticket and only if we decide to include them in the user profile screen

从 AuthProfileScreen 入口开始，检查已认证用户的个人资料如何显示，以及个人资料更新如何处理。检查 API 是否支持更改姓名、电子邮件、网站和个人资料图片，包括从照片库和相机获取输入。完成标准是：设置控件可以打开一个包含已确定个人资料字段的可编辑模态表单，并成功更新个人资料。
