feat: GL kit-connect ipk + one-button wizard + web dashboard for both platforms

Synology kit-connect (SPK):
- wizard.sh — one-button Keylink IT fleet setup (auto-runs on install)
- www/index.html — dark-themed local dashboard (same design as busrouter)
- bin/serve-dashboard.sh — busybox httpd on port 8089 with CGI endpoints
- start-stop-status updated to manage dashboard alongside daemon
- INFO updated: RT2600ac + RT6600ax compatibility noted
- postinst now runs wizard --auto for first-time setup

GL kit-connect (OpenWrt ipk):
- Makefile — DEPENDS: +curl +openssh-client +tailscale
- procd init — USE_PROCD=1, respawn with 5s delay
- connect-daemon.sh — Tailscale + reverse SSH (same as Synology version)
- connect-wizard.sh — one-button setup, idempotent, UCI config
- connect-register.sh — standalone hub registration
- www/kitconnect/index.html — dark-themed dashboard with wizard button
- www/kitconnect/wizard.cgi — web-triggered wizard endpoint
- UCI config at /etc/config/kitconnect

Both platforms share: same hub protocol, same Tailscale key, same port pool.
