fix: x4078 remote recovery + daemon wait-wedge bug + SPK rebuild

- docs/incident-log: mark x4078 recovered remotely via Tailscale (no
  physical access needed); document the recovery steps and root cause
- connect-daemon.sh: remove bare `wait` that wedged the retry loop
  forever on the setsid'd tailscaled child — once the tunnel failed the
  daemon could not self-heal until the package was restarted; now the
  main loop falls through start_tunnel (already blocking+retrying) and
  restarts the whole cycle cleanly
- SPK rebuilt (32839680 bytes) with the daemon fix included
- Also documents the two latent lessons: (1) a field router is only
  inaccessible when ALL three paths fail; (2) always check Tailscale +
  QuickConnect before assuming a truck roll is required
