P2-1 af: custom action herlaadLijsten laat de filterwissel de lijst herladen

Een Value Key op de component-instantie reset de pagingController niet (het
componentmodel is pagina-eigendom via wrapWithModel met
disposeOnWidgetDisposal = false), en er is geen builder-actie die
pagingController.refresh() genereert. Nieuwe custom action herlaadLijsten
wacht op de rebuild die de nieuwe datumVan/datumTot doorgeeft, loopt daarna
de element-tree af en roept refresh() aan op elke gemonteerde
PagedMasonryGridView. Gekoppeld als tweede actie op de ChoiceChips.

Op de telefoon-emulator (profile-build) getest: Alles -> Dit weekend geeft
meteen zaterdag 19 sep, Vandaag geeft dinsdag 15 sep, en een al geladen tab
(Activiteiten) ververst ook in plaats. De slider blijft staan, geen
paginaherlaad. Activiteiten/Vandaag is terecht leeg: services_4 geeft
vandaag 0 items, services_3 geeft er 9. dart analyze lib/: 0 errors.
