- weather_detail: scrollable hourly forecast (time, temp, description,
rain probability), data logic ported from old weather_detail_screen.cpp
- calendar_detail: scrollable list of all 10 events (summary + formatted
date/all_day), ported from old calendar_detail_screen.cpp
- mvg: scrollable departures list (line badge U/S colored, destination,
time/delay, cancellation), 1-minute refresh timer ported from old
mvg_screen.cpp
- all three use back_button widget (fixed bottom-left)
- main.cpp: Screen controller, navigates between screens via callbacks,
5-minute inactivity timeout -> home, per-screen tick() for refresh
Fetch weather/calendar/departures once in setup() after WiFi and dump
parsed fields to Serial, so JSON parsing against the three real
endpoints can be verified on hardware independently of the UI. API
layer itself unchanged (1:1 from m5stack-dashboard).
