Add server creation UI + user-server access assignment (step 3)
New admin-only page at /servers-settings (templates/servers.html) lists servers and creates new ones via POST /servers (ID/name/interface/ addresses/port, key pair generated server-side). Nav gets a "Servers" link. templates/users_settings.html gains a multi-select "Server Access" field wired to the server_ids support added to create-user/update-user in the previous commit, so admins can now actually assign non-admin users to specific servers through the UI.
