/**
 * Tests for executeAutoPick timer behavior across chess_clock and standard modes.
 *
 * chess_clock: auto-picks earn the increment (bank += increment) so a team that
 *              times out doesn't get permanently frozen at 0 on all future turns.
 * standard:    auto-picks reset the bank to exactly draftIncrementTime.
