My account page

The signed-in user's profile, password and own app tokens move from the
Settings card to their own page at #/account, ready for more user
functions. The sidebar footer links to it with the user's name. Users
can now set their own note; the page header shows when and from where
the session started, which the server now records. Settings keeps the
Users table, where your own row links to My account.
