perf: Sprint 19 P0/P1 性能优化落地
P0（高优先级）:
- P0-1: 确认数据库复合索引已存在（GORM tag），composite_index_test 验证通过
- P0-2: 连接池调优 MaxIdleConns 5→10, ConnMaxLifetime 30min→5min
- P0-3: Redis 智能探测（ProbeRedis），无 Redis 自动降级到纯内存模式
P1（中优先级）:
- P1-1: GZIP 压缩中间件（compress/gzip 标准库，零新依赖）
- P1-2: 权限缓存 TTL 30min→5min
- P1-3: Argon2id 启动自适应校准（CalibrateArgon2id）
历史优化（含本次提交）:
- L1Cache O(n)→O(1) LRU 重构
- Auth 中间件 DB 查询合并 + 5s L1 缓存
- Logger 异步化（4096 缓冲通道）
验证: go build/vet/test 41/41 PASS, govulncheck 无漏洞

fix: P0-02 prevent login attempt counter race condition
Add atomic Increment method to cache layers:
- L2Cache interface: add Increment method signature
- RedisCache: implement using Redis INCRBY
- L1Cache: implement with mutex-protected counter
- CacheManager: add Increment that updates both L1 and L2
Update incrementFailAttempts to use atomic Increment instead
of Get-Increment-Set pattern, preventing TOCTOU race.
