feat: weather conditions check from stroy-bot-main

Ports the weather check added to stroy-bot-main on 2026-10-16: daily
station weather, report positions with weather per shift and the AI
assessment of working conditions. Opens as ?page=weather&start=&end=
instead of the #weathercheck hash, and hub dates survive the way back.
