v2 host: portable desktop app (tray + FastAPI + WebView2 panel), unified config, HA control

Fold the Windows tray/daemon into one self-contained Clawdmeter.exe with a settings UI, and wire the host side of the watch features: - config.py: single %LOCALAPPDATA%\Clawdmeter\config.json (ha/buttons/settings), atomic writes, auto-migration from the old ha_config.json. - server.py: local FastAPI (127.0.0.1:8723) — GET/PUT /api/config (token masked), POST /api/ha/test, GET /api/ha/entities, GET /api/status. - web/index.html: brand-styled settings panel (Status/HA/Buttons/Settings tabs). - panel.py: pywebview/WebView2 window, launched as its own process (pywebview and pystray both want the main thread); tray "Settings" opens it via --panel. - daemon: HA command dispatch (toggle/bri/ct), dynamic button labels + index→ action mapping, watch-battery low warning toast, and the dimmer "dim" snapshot (dimreq → light_snapshot of the first entity) so the watch dial seeds from HA. - clawdmeter.spec / requirements: bundle fastapi+uvicorn+pywebview+webview backend. - build-exe.ps1: ASCII-only (Windows PowerShell 5.1 mangles em-dashes under cp1251).

+"""Local control-panel HTTP API for the Clawdmeter app (Phase 7, M1).
+
+A FastAPI app bound to 127.0.0.1 only. Serves the brand-styled web UI (``web/``)
+and a small REST API over the unified config (``config.py``). Runs in a daemon
+thread alongside the tray and the BLE daemon — one process, one exe.
+
+Security: bound to loopback; the HA token is masked in GET responses and never
+logged (mirrors ha_client / config).
