UX-13 P1: page shell and Home screen on a structured /status

- app/static/{index.html,app.css,app.js}: tabs (Home, Batteries, Settings,
  Setup), hash routes, phone bottom tabs, light/dark. Served inlined at "/";
  the route list is unchanged, and every URL is relative.
- app/homeview.py: /status gains state, now, batteries, plan, attention,
  month_peak and control beside the old fields. The plan is what the add-on
  does today: the arbitrage verdict (the same plan.arbitrage() call as the
  cycle), the monthly cycle, the peak limit, "follows the house".
- The Home plan chart has hover, tap and keyboard-focus tooltips: price bar =
  hour and price; block = what, when, why, kWh and EUR.
- Region preset and year: in config/model (for P2) and on the Home price line.
- test_home.py; test_messages part 8 scans every Home sentence; STYLE plan line.
