/**
* @file web_server.cpp
* @brief TACTICAL TIMER 2 — AsyncWebServer + SSE Web Dashboard 實作
*
* 嵌入完整 Web Dashboard HTML 於 PAGE_HTML PROGMEM 字串中，
* 透過 AsyncWebServer 伺服 HTTP GET/POST 路由，
* 以 SSE（Server-Sent Events）即時推播遊戲狀態到瀏覽器。
*
* 功能：
* - 模式切換、Start/Stop/Restart
* - Par Time、Random Delay、Drill 課題、Dry Fire BPM
* - Spy Listen/Stop/Clear、Preset 切換、Settings 雙向同步
* - History 瀏覽、詳情、刪除
* - SSE 事件：hit / gs / newgame / best / mode / settings / partime / drybeat
* - RWD：手機直式 / 橫式 / 平板 全適配
*
* 所有 HTTP handler 在 NetTask（Core 0）執行；
* sendXxx() 可從任何 Task 安全呼叫（AsyncWebServer 內部加鎖）。
*
* @version 3.0
