fix: revert TUNNEL_LOCAL_SSH_PORT to 2223, fix registry, add incident docs

- wizard.sh + connect.conf: TUNNEL_LOCAL_SSH_PORT back to 2223 (Synology SSH port)
- port-registry: renamed x6340 → x4662 (matches QuickConnect ID)
- port-registry: added MR2200ac mesh satellite note for x4662
- deployment checklist: added kit-connect section, post-deployment rules,
  incident log, and complete fleet port registry table
- memory: added fleet-router-inventory.md with full fleet state
- hub README: updated with current status and locations
