Replaced node name with uuid

[mdeitersen]

• Replaced node names with UUIDs in the scene graph so that node names do no have to be unique.
• Note: The implementation still requires testing, as the GUI will need adaptation and existing tests do not cover this change. Further adjustments may be needed to complete the implementation. Additionally, there is a need to test if the old tree YAML files are loaded correctly with the new UUID-based node structure.
• I did not adapt CapabilityExecutionStatus.msg and InsertNode.srv as they don’t seem to be used. These might be candidates for deletion if they’re no longer necessary.
