fix(invitation): 线下提号接入邀请返利并补发历史漏发，返利比例文案改读配置

- 线下提号（admin_pickups）不走订单结账流程，此前完全不发邀请返利；现于 Complete() 内按号主利润对半基数发放卖家侧返利
- 迁移 000086：invitation_rebate_ledgers 增加 source 列，唯一键调整为 (source, order_id, trade_role)，支持提号来源且保持幂等
- 新增 cmd/rebate-backfill 幂等补发脚本：默认预演，加 -apply 才写库
- 返利阶段文案不再写死 60%/30%/15%，改为按本次实际生效比例生成（钱包流水备注同步修正）
- 前台邀请页阶段标签/横幅/空态文案、移动端个人中心入口文案均改读接口配置，并修掉合法 0% 比例被 || 覆盖成 60% 的问题
- 新增单测：提号返利发放与幂等、cycleLabel 跟随后台配置
