fix(android): 钉 chrono <0.4.40 修复 arrow-arith 51 的 quarter 方法歧义 (E0034)

[原因] duckdb 0.10.2 非可选依赖 arrow 51 (→ arrow-arith 51)。
chrono 0.4.40+ 在 Datelike 新增 quarter(), 与 arrow-arith 自带的
ChronoDateExt::quarter 在 temporal.rs:90 产生 E0034 multiple applicable items。
桌面构建走 docker-build(web+OTA), 从未编译 arrow, 故只有 android CI 暴露。

[验证] cargo update -p chrono --precise 0.4.39 成功; 本机缺 MSVC 无法 cargo check,
  修复与 arrow-rs#6600 官方 workaround 一致 (chrono >=0.4.38, <0.4.40)
