fix(journal): drop broken WeatherCard from journal screen

The WeatherCard widget expected a flat shape (`current_temp`,
`condition`, `today_high`, ...) but the prep payload sends raw
OpenMeteo data nested under `forecast_json` per location. Every
field read as null, so the card pinned to the top of the journal
chat showed "null°" and "null/null" — visual noise covering up
the prep prose.

The prep prose itself already mentions weather plainly ("Weather at
home will reach a high of 15.9° with a 0% chance of precipitation"),
so the visual card is redundant. Removing it eliminates the bug
without losing any actual info; the weather data is still in
metadata.sections.weather if a future reader needs it.

Also deletes the unused widget file.
