feat(biz_project+meeting): 项目+会议软删除级联, admin/manager 双角色可删

biz_project* 5 表级联 (project/plan/assign/sponsor_assign/rating) + 会议链
biz_meeting* 6 表级联 admin-only → admin/manager 可删

DB:
- 5 ALTER TABLE 加 is_deleted TINYINT DEFAULT 0 NOT NULL (biz_project/plan/assign/sponsor_assign/rating)
- biz_meeting* 6 表已有 is_deleted 列 (上轮已 ALTER)

Domain (10 文件):
- 5 个 biz_project* 加 isDeleted 字段
- 6 个 biz_meeting* 加 isDeleted 字段
- (audit_log 列名特殊: 使用 deleted 字段存操作类型, 不冲突)

Mapper 接口 (10 文件):
- 5 个 project mapper 加 softDeleteByProjectId / softDeleteByProjectNo
- 5 个 meeting mapper 加 softDeleteByMeetingId
- BizMeetingMapper 加 selectIdListByProjectId (级联调用)

Mapper XML (10 文件):
- 所有 SELECT 加 is_deleted=0 过滤 (含 JOIN 子查询)
- 加 softDeleteByXxx UPDATE (10 处)
- BizMeetingMapper.xml 的 plan LEFT JOIN 加 proj.is_deleted=0 防悬挂

Service (3 文件):
- IBizProjectService.softDeleteCascade/Batch (含会议链调用)
- IBizMeetingService.softDeleteCascade/Batch
- BizProjectServiceImpl / BizMeetingServiceImpl @Transactional(rollbackFor=Exception.class)

Controller (2 文件):
- BizProjectController.DELETE 改 admin+manager 可删
- BizMeetingController.DELETE 改 admin+manager 可删 (放宽权限)
