fix(briefing): remove redundant current-conditions block; patch live temp into WeatherCard

The standalone current-conditions div showed just a bare temperature with no
forecast context, making the weather panel look incomplete. Now the live
temperature from /weather/current is patched directly into the WeatherCard's
current_temp so it stays fresh without a second display block.
