feat(omny): start osamroy sim at logical 0, speed up all sim stages 4x

- osamroy's sim_initial_position is now -25 (raw), so the simulated
  logical readback (raw + 25, per the controller's calibration-mark
  offset) starts at ~0 deg instead of 25 -- no rotation-to-zero needed
  just from starting a session.
- All 21 SimOMNYGalilMotor axes now have an explicit sim_velocity, set
  to 4x their previous implicit default (the _SimGalilAxis fallback of
  5.0 * 25600 = 128000 steps/s). 10.0 for the 20 translation axes
  (stppermm=51200); 5.716463414632019 for osamroy specifically, since
  its stppermm=89565.8666667 differs -- both correspond to the same
  512000 steps/s, i.e. a genuine 4x speedup for every stage.
