[Pre-Release] 1.4.1 - Further Bambu improvements

Further pre-release improvements to the experimental Bambu support.

Obtaining my own X2D highlighted several differences in how older Bambu systems like the X1C, A1, and A1 mini performed in my early testing and experimentation from the newer X2 and H2 series (and possibly P2). This is a first (majorly sweeping) pass at overhauling how Bambu works.

There are some majorly dramatic DB migrations in this one, so this is being cut as a pre-release and should be opt-in only if you need it for non-working bambu support needs, until I cut a final latest release that is known good.
