feat: 添加 G5 独立写入功能

- 新增 G5 数据库连接配置与可关闭的写入开关
- 在现有 legacy/G4 写入成功路径后，追加独立的 G5 写入流程
- G5 使用与 G4 相同的数据结构映射，但不写入 guid，由数据库自生成 int4 guid
- room_status 新增 G5 独立 upsert 写入路径，并保留旧表与 G5 表的独立开关
- 新增 G5 写入统计与启动摘要输出
- 更新 StatsCounters 和 StatsReporter 以支持 G5 统计
- 增加测试覆盖，确保 G5 写入逻辑与 room_status 的独立执行
- 新增 G5 相关数据库表结构 SQL 文件
