fix: non-disruptive startup checks + clean service lifecycle (v1.3.1)

- Env check is read-only when state is sane: no pineapd command-socket
  writes, no live pool-list commits, no wifi reload; pineapd restarts only
  when a runtime-sensitive UCI value changed or the daemon was down
- Failed monitor repairs now fail the startup contract instead of being
  reported as fixed; runtime pool state is read from active config
- Enterprise AP recovery runs only on device boot (PAGER_WEBUI_BOOT), not
  on every web-service restart
- serve() gates the HTTP port on startup checks with bounded retries and
  shuts down cleanly on SIGTERM/SIGINT; the recon watchdog waits
  interruptibly
- Recon uses a bounded userspace channel scheduler that drives both
  monitor radios over non-DFS channels, with preflight verification,
  serialized starts, and per-cycle error reporting
- payload.sh waits for real readiness on start, fully removes the boot
  service (stop + disable + delete) on stop, and surfaces a
  stopped-but-enabled boot service; deploy.sh refreshes the installed
  init script even when the service is stopped
- Bump version to 1.3.1
