Improve Error Handling, Add Named Pose Service, Optimize Motion Planning, and Enhance Feedback Mechanisms

- Set success flags on results when actions complete successfully in both `mtp_jeet_cart.cpp` and `mtp_jtc.cpp`, providing proper feedback to clients.
- Increased trajectory planning granularity by adjusting the divisor from 0.01 to 0.001 in `mtp_jtc_cart.cpp`, resulting in smoother robot movements.
- Introduced a new service `GetNamedPose` defined in `GetNamedPose.srv`, allowing nodes to request specific poses by name, enhancing modularity and reusability.
- Optimized motion planning in `mtp_jtc.cpp` by immediately succeeding when no movement is needed, reducing unnecessary computations.
- Updated `CMakeLists.txt` to include the new service
