LazyOwn: Default C2 Operator Credentials Enable Administrative Access to C2 Dashboard

LazyOwn RedTeam/APT Framework is an AI-powered C2 and red-team operations framework. Prior to 0.2.154, LazyOwn ships default C2 credentials LazyOwn and LazyOwn in payload.json and core/payload_schema.py and passes them unchanged to lazyc2.py HTTP Basic authentication, allowing any network-reachable attacker who knows the defaults to authenticate to the C2 dashboard with operator-level access. This issue is fixed in 0.2.154.
