The server now nulls a location on an explicit 0/0 advert and the WS nodeUpdate
event mirrors that: omitted lat/lng keeps the current position, null clears it.
patchNodeSummary used ?? so a clear was ignored.
The WS patch only updated nodes already in the paged cache, and with
staleTime Infinity nothing ever refetched — a node that came up after
page load could never appear on the map. The event carries a full
summary, so unknown nodes are appended to the cache directly. The
Nodes table keeps patch-only behavior since its cache is filter-scoped.
- LoadingPill shows loading/error state in MapView, NodeTable and ObserverTable
- new useInfinitePages hook shares the pagination logic between them
- patchNodeSummary/patchObserverSummary now keep references stable
- tests for loading states, observer updates and infinite paging
