Adds a new page titled "Import your settings" in the "Account basics"
section to document how to import user settings from an existing Zulip
account to a new Zulip account, and which settings will be imported.
Adds a question mark (?) icon linking to this help page from the
registration form when the import settings option is available.
Adds cross-links on related articles.
Fixes: #20918.
The phrasing "corner of the screen" wouldn't be accurate when the user
is doing a split screen or if the window or app is not taking up the
whole screen. Also, the use of "lower/upper" and "top/bottom" is not
consistent.
This standardizes on "corner of the app" and "bottom/top" when
referring to the location of app features on Desktop, Web, or Mobile.
This is in response to a support ticket where the user had a closed left
sidebar, had added an organization, and then couldn't figure out how to
switch organizations. They had googled and found "The desktop app makes it
easy to switch between different organizations" in our help docs, which was
not sufficiently helpful.
