更新启动警告键注释及对应的中英文资源文案，将“签名校验默认关闭”改为说明全局签名校验未强制启用，并明确指出未单独要求签名的端点可能存在请求重放风险；同时保留生产环境开启全局签名校验并配置强密钥的建议。
Review comments at @GameFrameX.Network.HTTP/BaseHttpHandler.cs:
- Around line 326-334: 将 NonceCache 的检查与写入改为原子占位：先用 TryAdd 争取插入；若 nonce
已存在，则读取其过期时间，未过期时沿用现有拒绝逻辑，已过期时用 TryUpdate 条件替换并在竞争失败时重试，确保同一 nonce 仅一个并发请求通过。
- Line 325: 更新 CheckSignVersionTwo，使其接收已解析的 timeTick，并将 nonce 过期时间基准设为
timestampUnixSeconds 与当前时间中的较晚者，再加上有效窗口，确保 nonce 在请求时间戳仍可通过校验期间保持有效；在调用处传入
timeTick，并补充未来时间戳请求的 nonce 重放回归测试。
Review comments at @GameFrameX.StartUp/AppStartUpBase.ByHTTPServer.cs:
- Around line 100-103: 将 `Setting.HttpRequireSign` 对应的 `LogHelper.Warning` 移到
`RunHttpServerAsync(...)` 成功返回之后，确保只有 HTTP 服务器启动成功时才记录“已启动”警告。

The new v2 signature mode is meant to stop replayed requests, but concurrent replays or replays of future-dated requests can still get through. Fix these before relying on v2 for internet-facing deployments.

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 7 functions across 8 files.

更新 `NonceCache` 的清理触发方式：不要在每次成功校验后因条目数超过阈值而全量扫描，改为按时间间隔节流，并用
`Interlocked.CompareExchange` 确保同一时刻仅一个请求执行清理；清理时仍移除已过期的 nonce。
建议对 key 和 value 做转义或长度前缀，并统一使用 CultureInfo.InvariantCulture 格式化。

建议增加一个并发重放测试：多个线程同时提交同一请求，断言只有一个请求成功。
依据学习记录：多线程服务端代码中，跨请求共享的静态集合如果存在未同步的读写，应标记为线程安全缺陷。
