chore: strip pipelock from Docker backend

- Remove pipelock_state_dir, _PIPELOCK_SUBDIR from bottle_state.py
- Remove proxy_plan: PipelockProxyPlan from DockerBottlePlan
- Remove EGRESS_PIPELOCK_CA_IN_CONTAINER from docker/egress.py
- Remove pipelock TLS init and proxy_plan population from launch.py
- Remove PipelockProxy import and pipelock_dir setup from prepare.py
- Remove pipelock volumes, daemon entry, and network alias from compose.py
- Remove pipelock mirroring entirely from egress_apply.py
- Agent HTTP_PROXY now always points at egress (no pipelock fallback)
