fix(design): align the simulator node designs with the packages they describe

[technolojin]

Description

Split of #13298 — the simulator slice.

VehicleDoorSimulator.node.yaml declares plugin: autoware::vehicle_door_simulator::DummyDoors, but autoware_vehicle_door_simulator builds its node with ament_auto_add_executable and registers no component with RCLCPP_COMPONENTS_REGISTER_NODE. The plugin: field is dropped; the design keeps its executable:.

DummyDiagPublisher declares the parameters its launcher passes: the required diagnostics come from the system-side parameter files, so the package defaults are empty and the node takes a second parameter file.

• fix(design): align the node designs with the packages they describe #13298 — the umbrella PR this is split from
• feat(autoware_sample_designs): compose the AD API, system and vehicle components from design modules autoware_launch#1976 — the launch counterpart; the reference system was built and run against this PR together with it

How was this PR tested?

• pre-commit run --files simulator/autoware_vehicle_door_simulator/design/VehicleDoorSimulator.node.yaml (Autoware System Design Format lint, prettier, yamllint) passes.
• Checked against CMakeLists.txt and the absence of RCLCPP_COMPONENTS_REGISTER_NODE in the package.
• The AutowareSample reference system was built and run with these designs against feat(autoware_sample_designs): compose the AD API, system and vehicle components from design modules autoware_launch#1976: colcon build --packages-select autoware_sample_designs succeeds with zero warnings and exports all four modes (Runtime, LoggingSimulation, PlanningSimulation, E2ESimulation), and planning simulation reaches autonomous mode.

Notes for reviewers

Design metadata only; no launch file or node source is touched.

Interface changes

None.

Effects on system behavior
