Add DaVinci example running over 2024 (sprucing24c2) data with particle refitting, add allPV functor collection

This MR adds the example to the user how to refit their decay tree (by essentially 2 lines). To do this, a sample is needed processed with Moore after the Technical Stop 1 of 2024, which includes the latest event model.

In addition, the tuple made in this MR

• Has nDownstreamTracks filled in the tuple
• Adds a new functor collection: allPV, which can also contain the PV uncertainties.

Needed for undrafting:

• The input DST needs to be placed in the standard DPA eos location (and the evt_max lowered to e.g. 5k).

Goes together with: Rec!3995 (merged) Moore!3622 (merged) LHCb!4637 (merged)

Closes #210 (closed)
