Set a user's bots and workspaces in their own groups, saved at once

Take the Bots and Workspaces pickers out of the user form. A user's
settings page lists what they reach in two groups, like a workspace's
Bots group: each row links to its settings and can be taken away, and
a select adds one, saved straight away through users/add-access and
users/remove-access (setUserGrant).
