fix: coolify_configs table missing + miniwebs real status

- Add coolify_config.go model (missing from worktree branch)
- Add CoolifyConfig to normal-startup AutoMigrate → creates table on next start
- Fix miniwebs tab: m.activo is not in API response; fallback to
  vcard.estado (true/false) to show real status instead of always Inactiva
- Improve miniwebs row: show url, user name, vcard status badge
