Fix some lingering installation sharp-edges

[NishanthJKumar]

• On M2T2. Maybe need to add tmux into the pixi.toml. Not sure what the attr issue is as couldn't reproduce previously

  On the M2T2 pixi run demo, to get it working, I had to
  sudo apt install tmux
  pixi add attrs (to solve the below error)
  File "/mnt/data/projects/robotics/tiptop/M2T2/.pixi/envs/default/lib/python3.10/site-packages/omega
  conf/_utils.py", line 444, in is_attr_class                                                                                                                                                                                                   return attr.has(obj)
  AttributeError: module 'attr' has no attribute 'has'                                                                                                                                                                                                    │ERROR:    Application startup failed. Exiting.
  Running the pixi add attrs updated my pixi.toml to add this line
  attrs = ">=25.4.0,<26"
  

• In cuTAMP, have a simple script that loads a curobo YML file and runs a test with it or something, similar to here but using rerun and maybe sampling a valid joint position and moving there from retract config: https://curobo.org/tutorials/1_robot_configuration.html#test-robot-configuration
• Have a way to visualize gripper spheres properly, and defining end-effector link transform in URDF so approaches are good?
• pyrealsense2 dependency for Realsense? Maybe just add it in general
• Better registry for cuTAMP so don't need to modify and add so many methods
• Should we have script to generate calibration board or just provide a PDF for people to print out that assumes our default? That script also needs cleaning up at some point (not critical for now)
