mod: fix clock bugs, add NTP auto-sync, show clock in all headers

- Fix SetTimeActivity immediately dismissing by changing wasReleased to
  wasPressed for all button inputs (matching other subactivities)
- Extract NTP sync into shared TimeSync utility (startNtpSync,
  waitForNtpSync, stopNtpSync) and trigger non-blocking NTP sync on
  every WiFi connection
- Move clock rendering into drawHeader (BaseTheme + LyraTheme) so it
  appears on all screens with a header, positioned symmetrically with
  the battery icon (12px margin, same Y offset, SMALL_FONT_ID)
- Add per-minute auto-refresh on home screen so clock updates without
  button press
- Add RTC time debug log on boot to verify time persistence across
  deep sleep
