新建 partition component

[olivierauverlot]

Provides a mechanism to define custom pagination rules.

It allows splitting records on the generated page based on a user-specified partitioning criterion, ensuring controlled data distribution across pages.

The compact control does not reveal the active facet while it is closed: the button says Classes, while the active Constitution value is only visible after opening the menu.

Added optional dropdown_title for compact facets. Item rows are streamed after the dropdown button, so the template cannot derive the active item title before rendering that button. The query can now supply the selected title explicitly; it defaults to description when omitted.

My latest commit is a proposed improvement. The description property can now be used in both modes (normal and compact). I kept dropdown_title, but it is now used to display text on the selector when no facet has been selected by the user. I also added the selected_facet property to indicate the selected facet. This seems more consistent to me and allows for greater flexibility when using the component.

It’s just a detail, but I’m not a big fan of the name facet for this component. I prefer partition, which seems more appropriate to me.
