POST /api/config/apply now takes effect via a graceful SELF-RESTART instead of
logging "restart needed" and leaving stale in-process singletons (the CF client
is built once at startup, so a rotated Cloudflare token never applied until a
manual LXC restart). Container is restart:unless-stopped, so a clean os.Exit(0)
auto-restarts with fresh config.
- New gracefulSelfRestart helper behind an injectable Restarter seam (Router.restart
+ SetRestarter) so the exit is unit-testable.
- configApply: no-op guard (byte-identical re-push → no write, no restart), else
write → 200 (flushed) → restart. Removed stale "restart needed" wording.
- Removed the dead OnConfigApplied hook (Phase-1-retired infra-backup push; the
self-restart reloads everything and a fresh report is pushed on startup).
- New POST /api/selfrestart (auth+CSRF via /api/ mount) + "Vezérlő újraindítása"
settings button: confirm → POST → poll GET / every 2s → reload.
- Tests: changed→restart once; identical→not called (companion); invalid→not called;
selfrestart→restart once.
