refactor(network): drop dead 'migrate apps to new subnet' machinery

The migrate/ helpers were either uncallable or no-ops:

- migrateAppsToNewNetwork + updateComposeFileNetwork: never called from
  anywhere. The intended sed-on-compose subnet rewrite would also have
  fought the tag system / network_resources DB.
- checkAppNetworkCompatibility: called from updateDockerNetworkConfig as
  a gate, but never explicitly returns, so it's effectively always-true
  and both branches do the same work. Pure noise.
- getInstalledApps: only used by the above.
- updateDockerNetworkConfig: collapses to a 2-line 'CFG := docker's
  reported subnet' adoption — inlined into check_docker_network.sh as
  adoptDockerSubnet(), which is what it actually does.

The legitimate 'subnet changed, refresh apps' path is already covered by
the idempotent per-app reinstall (dockerInstallApp ... reset_network=true
→ clears DB allocations → installer re-runs → ipUpdateComposeTags picks
fresh IPs from the current CFG_NETWORK_SUBNET). Migration (infrastructure
regen) vs restore (data) stays clean: reinstall regenerates compose+IPs,
restore lays data on top. No new pathway needed.

Files dropped:
  scripts/docker/network/migrate/migrate_apps_to_new_network.sh
  scripts/docker/network/migrate/migrate_check_app_network_compatibility.sh
  scripts/docker/network/migrate/migrate_get_installed_apps.sh
  scripts/docker/network/migrate/migrate_update_compose_file_network.sh
  scripts/docker/network/migrate/migrate_update_docker_network_config.sh

Plus the now-empty migrate/ subdir; files_docker.sh regenerated to drop
the references.
