role select channels FTs: equip Earthman deck in setUp — fixes no-deck guard block

The role-select.js no-deck guard (added with e512e94) shows a warning instead of
opening #id_role_select when data-equipped-deck is empty. Three RoleSelectChannelsTest
setups didn't equip a deck for the founder, so the card-stack click never opened the
modal and all three failed with NoSuchElementException on #id_role_select.
Only the founder needs equipping — other gamers' roles are ORM-assigned, no browser click.
