This is what I'd do, and please bear in mind that I'm being overly retentive on this:

- close propane valve at panel of fridge - connect BBQ tank to fridge, open valve on tank - check for leaks at nut on end of tube on fridge where BBQ tank connects. (I really really really doubt there will be any leak where that nut is (brazed?) to that tube but it takes seconds to check) - open fridge LP valve - check for leaks between valve and thermostat (doubt there are any at those points)

Propane should pass through the thermostat regardless of thermostat dial setting. But as you surmised, setting it to Max will allow the most fuel through.

To check for leaks downstream of the safety valve, I wonder if there's an (NPT ??) plug that could be inserted in place of the burner jet. This way you could test for leaks where small tube joins the safety valve and burner box. OR, just cover the jet with a piece of soft rubber to do same?

This is a guess, but even if there were a minute leak at union between the small line you cleaned and safety valve or combustion box, the spark and flame are contained inside the combustion box; I can't see how any fuel leaking at unions outside of the box could be ignited by that spark. And if you flood the combustion box, and the ignitor is working, you'd hear a "poof" or "pop" of fuel igniting.
