fix(admin): offer --purge for users who own repositories and show roles

admin user delete of a user who owns repositories failed with Gitea's raw
HTTP 422. The error now says what blocks the deletion and how to proceed,
and --purge deletes the account with its repositories, packages and
organization memberships after typing the username on a terminal.

admin user list shows ROLE and STATUS columns (admin, restricted, user;
active, inactive, login prohibited) with the email and creation date
instead of admin=true/active=true cells, and --query filters by username,
name or email. admin user view shows the account instead of its list
row. create asks for a missing username and email address with readable
labels and re-asks for invalid answers, mutations print ✓ lines, usernames
complete, and every command has examples.
