DOC: add preview of AmpForm-DPD model deserialization

[redeboer]

Added a page for Lc to pKpi that illustrates ComPWA/ampform-dpd#132 (preview).

Warning

The model validation does not work yet, for now the page just illustrates the symbolic rendering of the deserialized model. Keep an eye on ComPWA/ampform-dpd#133 for upcoming fixes.

@mmikhasenko the page has been converted from a Jupyter notebook with MyST syntax and is not yet optimal for Quarto. On the road today, hope to get back to that later today. The PR should be merged before tomorrow afternoon.

Looks great, @redeboer.
I could not spot any problems right away: maybe it matches once the nan is solved.

[mmikhasenko]

Combination of s (GeV^2), and masses (GeV) does not look right, if the order of the argument changes (production vs decay of resonance)

[mmikhasenko]

p^{2L} is missing.

my form-factor includes z^{2l} in the numerator, that is why there is no p^{2l+1} in julia code. Just 2p/sqrt{s}

[redeboer]

maybe it matches once the nan is solved.

For that it would be easiest to get a section with checksums for dynamics. But indeed perhaps the points you pointed out might fix it already.

[redeboer]

I'm doubting btw between merging this PR for now to get at least the preview up or addressing the issues first. Don't think I can handle that quickly because it might require a new prerelease of AmpForm-DPD.

Good point, though more of a design problem + latex rendering problem? You would just have to square the mass. But yeah if there is some argument swapping going on programmatically this is tricky...

[redeboer]

@mmikhasenko seeing that CI takes some time, I would prefer to merge this one (and #45?) asap. Remaining issues will be addressed through ComPWA/ampform-dpd#133 and a follow-up PR here.

[redeboer]

Ah sorry, hadn't noticed that the requirement for an approval was switched off... so it automerged already
