Subject: [PATCH] Accept _APP_MIGRATION_HOST too when matching local source
 endpoint

_APP_DOMAIN is the public host users paste from console, but programmatic
migrations that leave `endpoint` blank default to _APP_MIGRATION_HOST in
processMigration. Both are valid references to this cluster; checking only
_APP_DOMAIN rejected the second pattern (e.g. CI tests pass the internal
host directly) and routed legitimate intra-cluster migrations to SDK.
