Bind the remote PostgreSQL port to an explicit interface.

The role publishes postgresql_publish directly to Podman. This playbook overrides the role's loopback default with "5432:5432", which can bind PostgreSQL on all host interfaces. Bind it to the approved management interface and enforce the intended firewall scope.

In `@development/playbooks/remote-database/remote-database.yaml` at line 15,
Update the PostgreSQL port mapping in the remote database playbook to bind host
port 5432 to the approved management interface instead of all host interfaces,
preserving the container port and enforcing the intended firewall scope.

## Architecture

IOP runs as a set of containerized services managed via podman quadlets on the shared `foreman-core-network` (bridge, `10.130.0.0/24`), alongside Foreman, Postgres, and other co-located services. See [Network Architecture](network.md) for the host/bridge split, unix sockets, and published ports.

The subnet matches the former `iop-core-network` so the gateway image nginx resolver (`10.130.0.1`) can resolve upstream service names. The gateway is registered as a Foreman smart proxy at `https://iop-core-gateway:8443` (host publish remains `127.0.0.1:24443` for host-side tools and tests).

### Network

All IOP containers join the `iop-core-network` bridge network (`10.130.0.0/24`, gateway `10.130.0.1`). Containers communicate with each other by container name within this network.

Database connectivity uses `host.containers.internal:5432` to reach the host's PostgreSQL instance. SSL is disabled for these internal connections.

The gateway binds only to `127.0.0.1:24443` so it is not externally accessible.
All IOP containers join `foreman-core-network` and reach Postgres at `postgresql:5432`. The gateway is published on host loopback as `127.0.0.1:24443` (container port `8443`) so it is not externally accessible; the Foreman container talks to it as `https://iop-core-gateway:8443`. The gateway relays to Foreman via `https://host.containers.internal` (Apache on the host). See [Network Architecture](network.md).

Enable upstream TLS identity verification.

The relay template sets proxy_ssl_name to the Foreman FQDN, but NGINX defaults proxy_ssl_server_name and proxy_ssl_verify to off. Add proxy_ssl_server_name on;, proxy_ssl_verify on;, and proxy_ssl_trusted_certificate /etc/nginx/certs/ca.crt;. Document these settings beside the proxy_pass example in docs/architecture/network.md.

Advisor and vulnerability services use PostgreSQL foreign data wrappers (FDW) to query the inventory database directly, avoiding REST API overhead for bulk data access.

IOP app containers still connect as `postgresql:5432` on the bridge. FDW is different: Ansible sets up the foreign server from the host (`login_host: 127.0.0.1`, the published IPv4 port), and `CREATE SERVER` stores `host=127.0.0.1`, which Postgres interprets inside its own container so advisor/vuln stay on-box instead of hairpinning through the bridge. See [PostgreSQL from three vantage points](network.md#postgresql-from-three-vantage-points).
