* fix: harden backup import for duplicate platform stats

- 修复 replace 模式下主库清空失败仍继续导入的问题。
- 导入前对 platform_stats 重复键做聚合（count 累加），并统一时间戳判重格式。
- 非法 count 按 0 处理并告警（限流），补充对应测试。

* refactor: improve robustness and readability of platform stats import

- 告警上限魔法数字提取为模块常量 PLATFORM_STATS_INVALID_COUNT_WARN_LIMIT
- 抽取 parse_count 内联函数，消除重复的 try/except 分支
- 存储行的 timestamp 同步写入规范化值，避免落库格式混用
- 补充测试：已有行 count 非法、告警限流、replace 模式中断断言

* fix: normalize invalid platform_stats count for non-duplicate rows

* fix: avoid merging invalid platform_stats timestamps

* refactor: simplify platform stats merge and normalize naive UTC

* refactor: inline platform stats merge helpers

* refactor: flatten platform stats merge flow

* refactor: harden platform stats merge key handling

* refactor: streamline platform stats preprocessing

* refactor: simplify platform stats merge helpers

* refactor: inline platform stats merge normalization

* refactor: extract platform stats merge helpers

* refactor: simplify platform stats preprocessing flow
