Steps to reproduce issue

When using a string parameter for a ros2 Node, if you load a parameter file that sets that parameter with a map value, the default string value is used, and the yaml map is ignored.
Instead a type error should be thrown.

Reproducible example:

node:

class RuntimeCameraManagerNode(Node):
    def __init__(self):
        super().__init__("camera_manager")

        # Camera process tracking
        self.active_cameras: dict[str, asyncio.subprocess.Process] = {}
        self.monitor_tasks: dict[str, asyncio.Task] = {}
        self.shutdown_requested: bool = False
        self.camera_configs: dict[str, CameraConfig] = {}
        # Declare camera configuration parameters
        self.declare_parameter(
            name="cameras",
            value="{}",
            descriptor=ParameterDescriptor(
                name="cameras",
                type=ParameterType.PARAMETER_STRING,
                description="Dictionary containing camera config info",
                additional_constraints="Must be a valid YAML/JSON formatted dictionary string",
                read_only=False,
            ),
        )

And the input parameters file cameras_config.yaml is:

camera_manager:
  ros__parameters:
    cameras:
      zivid_0:
        camera_location: "cieling-front-left"
        virtual_camera_path: "/usr/share/Zivid/data/FileCameraZivid2PlusM60.zfc"

When run with:
ros2 run camera_manager camera_manager --ros-args --params-file cameras_config.yaml
the default value of "{}" is used rather than throwing an exception
I see that ros is auomatically loading:
camera.zivid_0.camera_location and camera.zivid_0.virtual_camera_path as Parameter instances in node._parameter_overrides

Expected behavior

When run with:
ros2 run camera_manager camera_manager --ros-args --params-file cameras_config.yaml
the default value of "{}" is used rather than throwing an exception

Actual behavior

the default value of "{}" is used
I see that ros is auomatically loading:
camera.zivid_0.camera_location and camera.zivid_0.virtual_camera_path as Parameter instances in node._parameter_overrides

Here is a possible solution that may need some tweaking for other use cases:

class TypeCheckedNode(Node):
    def __key_to_dict(self, map_data: dict, key_with_periods: str, value: Parameter):
        if "." in key_with_periods:
            key, rest = key_with_periods.split(".", 1)
            if key not in map_data:
                map_data[key] = {}
            self.__key_to_dict(map_data[key], rest, value)
        else:
            map_data[key_with_periods] = value.value

    def declare_parameters(  # noqa: C901
        self,
        namespace: str,
        parameters: list[tuple[str] | tuple[str, Parameter.Type] | tuple[str, typing.Any, ParameterDescriptor],],
        ignore_override: bool = False,
    ) -> list[Parameter]:
        """Declare a list of parameters.

        The tuples in the given parameter list shall contain the name for each parameter,
        optionally providing a value and a descriptor.
        For each entry in the list, a parameter with a name of "namespace.name"
        will be declared.
        The resulting value for each declared parameter will be returned, considering
        parameter overrides set upon node creation as the first choice,
        or provided parameter values as the second one.

        The name expansion is naive, so if you set the namespace to be "foo.",
        then the resulting parameter names will be like "foo..name".
        However, if the namespace is an empty string, then no leading '.' will be
        placed before each name, which would have been the case when naively
        expanding "namespace.name".
        This allows you to declare several parameters at once without a namespace.

        This method, if successful, will result in any callback registered with
        :func:`add_on_set_parameters_callback` to be called once for each parameter.
        If one of those calls fail, an exception will be raised and the remaining parameters will
        not be declared.
