Focusing the T-axis and framing the sample on the XY stage are both done
by eye, but the controls were in the main window and the T3R panel, so
the operator had to look away from the video to move anything.
Adds gui/jog_panel.py with two panels, laid out in a column to the right
of the camera image:
T3RJogPanel per-axis enable, hold-to-jog ◀/▶, live position, and a
per-channel microstep combo (SET_MICROSTEP is per channel
on this controller). Jog velocity and acceleration are
shared by the four axes.
BBDJogPanel an X/Y jog pad, step size, and velocity/acceleration.
The stage runs closed-loop servos, so there is no
microstepping to set — the panel says so rather than
offering a control that does nothing.
The T3R's JOG is a continuous velocity move, so the button holds it and
the release stops it; the BBD has no such command, so a held button
repeats a short relative move the way the main window already does.
Only axes this panel started are ever stopped — closing the window or
hitting "Stop jogging" can't cut a scan's rotation short.
Both panels take the driver and worker the main window already owns, so
a jog here is the same command as a jog there. The BBD202 worker grows
a set_velocity command, and its jog now carries the step with it instead
of the caller writing _jog_step onto the worker from the GUI thread.
