Weather: icon-left/temp-right layout, feels-like/high-low/rain

chance, and an hourly temperature graph

- Current conditions block redone horizontally (icon left, big temp
  + description + an extras line on the right) instead of stacked
  vertically.
- New extras line: "feels like" (apparent_temperature), today's
  high/low, and rain chance (precipitation_probability_max) -- each
  independently toggleable in settings, all on by default. Switched
  from the legacy current_weather=true param to Open-Meteo's current=
  param, since that's what exposes apparent_temperature; confirmed
  field names/formats live before wiring them in.
- New hourly-today temperature graph (also toggleable): a polyline
  across today's 24 hourly points, min/max temps labeled at their
  points, a red dot marking the current hour, and hour labels along
  the bottom.
- When both the graph and the daily forecast strip are shown, they
  split the remaining vertical space; either can be toggled off to
  give the other more room, matching how forecast_days already
  worked.
