help-docs: Improve "Logging in" and "Switching between organizations".

Improves step-by-step instructions for Desktop users by directing
users to the relevant items in the left sidebar or top menu bar
without using an obscure keyboard shortcut.

Adds tip macro with instructions for toggling the app's left sidebar
via the top menu bar.

Moves the proxy settings and custom certificate info into a warning
block instead of the main instructions flow given they are rarely
needed for Logging in.

Adds a Related Articles section to "Switching between organizations"
so that users can access the information for setting an organization
profile picture from there instead of an oddly placed warning block.

Also adds links to "Logging in", "Logging out", and "Deactivate your
account", and lists them in each other's Related articles sections.
