c26f116a98 fix(deploy): harden production container and bootstrap security (#1014)
* fix(deploy): harden production container and bootstrap security

- Replace --network=host with explicit port mapping (-p 3000:3000) to
  restore Docker network isolation. The prior config gave the container
  full access to the host network namespace including the Cloud SQL Auth
  Proxy on localhost:5432. (CWE-668)

- Support pinned image versions via IRONCLAW_VERSION env var instead of
  always pulling :latest. Mutable tags allow uncontrolled deployments
  if the registry is compromised or a broken image is pushed. Falls back
  to :latest when unset for backwards compatibility. (CWE-829)

- Add SHA256 checksum verification after downloading the Cloud SQL Auth
  Proxy binary. The prior script executed an unverified binary downloaded
  over the network with direct access to the production database.
  (CWE-494)
