feat(caddy): import Caddyfile routes on startup if table is empty

On every startup, if Caddy is already enabled but the caddy table has no
routes (e.g. after a re-deploy), importCaddyfileRoutes() is called so the
static GhostGrid entries from /etc/caddy/Caddyfile are seeded automatically.
Also ensures deploy.sh is executable via proxmox-ghostgrid.sh.
