Stage 17 (contour round 2): Grafana Live/reload, rate-limit, iOS reconnect, hint/plaque/make-move UX

- Grafana: disable Live (GF_LIVE_MAX_CONNECTIONS=0) so its WebSocket no longer trips caddy Basic-Auth and re-prompts; admin console gains a Grafana nav link
- deploy: force-recreate config-only services so reseeded Grafana dashboards / Caddyfile are actually picked up (the move-duration panel was invisible because the bind-mount went stale)
- rate-limit: raise per-user budget 120/40 -> 300/80; UI skips reloading on the echo of the player's own move (fewer requests, no double-load)
- iOS/Telegram reconnect: suppress the connection banner while backgrounded and for a short grace after resume; reconnect silently; wire visibilitychange + pageshow/pagehide + Telegram activated/deactivated (Bot API 8.0)
- hint button disabled when 0 hints remain; nudge button shows a disabled state on your own turn
- players plaque: invert so the active seat pops (accent chip, raised) and others recede
- make-move UX: a direct ✅ commit button (no hold/popover); the Shuffle tab becomes ↩️ Reset while tiles are pending
