chore: baseline codex hardening before lifecycle refactor

Snapshots the in-flight hardening work so subsequent reconcile/Quadlet
phases land on a clean before/after diff.

Changes:
- core/container/src/podman_client.rs: image_uses_insecure_registry()
  whitelist for the OVH (146.59.87.168:3000) and legacy Hetzner
  (23.182.128.160:3000) HTTP mirrors; podman_network_settings() lifts
  custom networks into the Networks map so containers can join them.
- core/archipelago/src/container/prod_orchestrator.rs:
  ensure_container_network() creates per-manifest networks on demand;
  apply_data_uid() now goes through host_sudo for mkdir -p + chown so
  bind-mount roots get created and chowned without password prompts.
- core/archipelago/src/api/rpc/package/{install,update,stacks}.rs:
  podman pull adds --tls-verify=false only for whitelisted registries.
- core/archipelago/src/bootstrap.rs: removes stale dev-mode systemd
  override on startup (live nodes carried it from old installers).
- core/archipelago/src/config.rs: ignore ARCHIPELAGO_DEV_MODE in prod
  binaries — it had been silently rerouting volumes to /tmp.
- apps/bitcoin-{core,knots}/manifest.yml: locate bitcoind at runtime
  so image-layout differences don't break entrypoint.
- scripts/app-catalog-image-smoke-test.py: production catalog/image
  smoke test that probes a target node before users click Install.
- .gitignore: cover .codex, .pnpm-store, __pycache__, *.bak.

Removes filebrowser.rs.bak and two stale catalog.json.bak files
(verified identical to live counterparts).
