/**
 * restart.ts — POST /tiger/restart
 *
 * Trigger a Tiger container restart via the gateway watchdog script.
 *
 * Why a watchdog script?
 *   A simple `docker restart` would work, but the OpenClaw gateway needs
 *   specific flags (--allow-unconfigured) and the correct sequence to
 *   come back up cleanly.  The watchdog handles all of that.
 *
 * The watchdog lives at /root/gateway-watchdog.sh on the VPS host.
 *
 * POST /tiger/restart
 *   Optional body: { "reason": "string" }  — logged but not used operationally
 *
 * Response:
 *   { ok: true, message: "..." }   — restart was triggered
 *   { ok: false, error: "..." }    — something went wrong
