/**
 * Enriches the seed org with users matching the approval templates' common role
 * labels (董事长 / 总经理 / 成控总监 / 各成本会计 / 出纳 / 法务经理 / 保密员 / 资料员 …).
 *
 * Why: workflow nodes carry role labels; with only 6 demo users NodeAssigneeResolver
 * dumped most approvals on admin. Seeding the matching real users lets the resolver
 * route each node to a distinct person, so multi-user 待办 is realistic.
 *
 * Idempotent + non-destructive: runs after the base seeder, only adds users that are
 * missing (guard on a sentinel login). All accounts use password 123456.
