feat(weather)!: add /thuyvan flood alerts for Tân Thuận

/thuyvan shows the 5-day tide-peak forecast at Phú An and Nhà Bè from
the Đài KTTV Nam Bộ bulletin PDF, the Open-Meteo rain forecast, and live
VNDMS river gauges within 30 km. /thuyvan_subscribe opts a chat into a
10:30 ICT push, retried at 12:30, sent only when a forecast peak reaches
báo động I (1.40 m) or a day's rain reaches 50 mm. A missing or stale
bulletin fails the push instead of reading as no risk.

The thoitiet module is renamed to weather; the /thoitiet* commands keep
their names.

BREAKING CHANGE: the module key is now "weather". A MODULES list that
names thoitiet fails at startup and must name weather instead.
