Issues testing 3.6.1 beta

Tested the code night of Sept 16, with software up to a65413da (the latest commit at the time of testing). Found several major issues. Here is a list of all things:

1. Guiding with scheduler gets suspended right away and never restarts. I've tracked that issue down to this line, https://invent.kde.org/education/kstars/-/blob/master/kstars/ekos/capture/capture.cpp#L6060 but that line makes sure the exposure isn't a Light frame, and yet all I'm capturing are Light frames. Perhaps the getFrameType() is not set up yet? I commented out those lines, restarted, and guiding no longer gets suspended. This is a show-stopper for internal guiding.

2. My guiding exposure gets reset to 1s on restart, even though I've set 5s several times. I can check again, but it has happened several times. Doesn't consistently happen, though.

3. FIXED. Polar alignment in refresh mode with the plate-solve scheme never refreshes. The move-star scheme works. I discovered that the refresh algorithm-choice parameter is not being set anywhere. It can't have always been this way...in any event, I've written !743 (closed) to fix it. Seems to work now in the simulator.

4. When I first started, all tabs had many things disabled. I needed to change trains, then change them back to get things working. After that, on restarts, things worked. I'm guessing there's a stored parameter that isn't initialized at first. This happened on the simulator too. Leaving for you folks to debug.

5. I suspect the guide tab is defaulting to the Primary train (it should default to Secondary).

6. At the end of the night, the scheduler job finished, the scheduler shut down and should have parked but didn't. Perhaps it's not reading the "Shutdown --> Park Mount" parameter properly, similar to the other parameter issues?
