CoderFX dff77e105d Add PiSugar 3 shutdown/startup scripts and watchdog

PiSugar 3 users need graceful shutdown with e-ink feedback, boot-loop
prevention when charging from dead battery, and automatic recovery
when pisugar-server loses I2C connection after MCU wake.

- safe-shutdown.sh: stops pwnagotchi, draws sleeping face on e-ink,
  powers off. Boot-loop guard skips shutdown when battery <10% and
  charging.
- pisugar-watchdog.sh + systemd timer: detects MCU wake from deep
  sleep and restarts pisugar-server when I2C is present but daemon
  reports disconnected.
- epd-shutdown.py / epd-startup.py: e-ink display faces for
  Waveshare V4. Exit silently on non-V4 displays.
