// Regression coverage for a real bug the user reported: moving a driver from one team to
// another (by ticking them on the new team's edit form - there is no separate "move"
// action) used to only ever ADD the driver to the new team, never remove them from the
// old one, so the same driver ended up listed on two teams at once. Also covers the two
// related findings from the same investigation: getTeamDriverPool used to ignore the
// event's class/participant scoping entirely (showing every driver in the club), and
// deleting a driver left them behind in any team's roster forever.
//
// The event/session fixtures are seeded directly rather than driven through the 4-step
// race wizard (already covered by browser_race_setup.js) - only team management itself is
// under test here, and the Teams section only renders once a team_race session exists
// (see showTeamsSection in event_manager_controller.js).
