Redesign weather popup and auto-refresh forecast

Replace the inline detail flyout with a two-column hero: location chip
and large temperature on the left, big condition icon on the right.
Stats (Feels / Wind / Humidity) move below as caps-labeled columns,
separated from the forecast by a thin divider. Forecast cells now lead
with the day icon and put the day name above hi/lo temps.

Drop the Refresh and wttr.in pill buttons; a Timer refreshes the
forecast every refreshMinutes (default 15). The interval is exposed
through the Settings panel — Bar -> Weather has a gear that opens a
SpinBox-backed form, persisted as "settings": { "refreshMinutes": N }
in shell.json.
