ykxmz 1.5.0：修复手表端 TLS 证书校验 + MTU 修复网络稳定性

被控端
- 修复 MTU 问题：夹 MSS + 路径 MTU 探测（公网可用率 48% -> 100%）
- 复用 HTTP 连接（免掉每次新建 TLS 的 30% 握手失败）
- 每分钟回头找局域网，自动切回快 400 倍的路径
- 画面心跳帧：静止时省流量，客户端仍知道流是活的
- 锁屏时给出可操作的提示

手表端
- 内置 GTS Root R4 / GlobalSign Root CA，修 SSLHandshakeException
- 连接错误翻译成人话（证书/时间/解析/超时分别提示）
- 经中转连上后用服务器报的地址刷新已配对记录
- 新增局域网连接页面、服务器延迟检测

服务器端
- 支持 chunked 请求体（修每 16 秒一次的连接错乱与大面积 502）
- 网络调优脚本 net-tune.sh（开机自动应用）
- 管理页：批量删除、网络体检、下载区
- 隧道改 HTTP/2 + 双连接
