feat(ingress/fabric_legacy): expose legacy_resource_details from utility module (#548) (#549)

Re-export the underlying nginx_gateway_fabric module's
legacy_resource_details so ingress values (basic auth password, base
domain, per-rule domains) reach level2's concat in facets-iac and show
up in the Facets UI. Without this passthrough, level2's
lookup(local.module_<key>, "legacy_resource_details", []) falls back to
[] and the UI's resource-values panel is empty.

Applied to all three flavors (aws, azure, gcp) for parity.
