Add infra-tool: infrastructure registry with Incus container deployment

Service registry & discovery system that aggregates infrastructure metadata
from Incus, K8s, APISIX, and BunnyCDN into NocoDB. Includes FastAPI HTTP API,
systemd timer for 15-min auto-sync, and dual-mode collectors (REST API for
container deployment, CLI/SSH fallback for local use). Deployed to jp1:infra-tool
with Tailscale socket proxy for host network visibility.
