feat(weather): add refresh button and return card data from refresh endpoint

Add a refresh button (↻) to the weather section header in BriefingView so
users can manually re-fetch weather data (needed after deploying the hourly
precip changes to populate the cache). Update the existing POST
/api/briefing/weather/refresh endpoint to return full card data instead of
just location keys.
