Improves app UI performance, better UX

[Yurii-IvoryFace]

Improved app routing speed:

• avg improvement per page switch 10-30ms
• huge improvement in Trading Analytics tab, over 300ms saved on page loading when selected 100+ items in table

What was done:

1. Swithed DataTable to use isFetching, this improves UX on huge tables loading

• huge save up to 300ms (on r7 5700x3d), you can revert it back to use isLoading for small tables - prevents preloader blinks

2. Lazy-loading routes + prefetch on hover. Uses custom routeLoaders.ts

• minor save

3. Context Value Memo, nav-links memo, and List Components memo (ItemName, RivenPreview, DisplayPlatinum).

old: each AppContextProvider render = new objects = whole tree re-render even if nothing changed
new; re-render only when something really changed

• minor save

4. Fixes issue with doble API call on each ItemName creation, also in RivenPreview, uses cache.context.tsx.

export const ItemName = memo(function ItemName(...) {
  // every component instance calls 2 times >
  const { data: tradableItems } = useQuery({
    queryKey: ["cache_items"],
    queryFn: () => api.cache.getTradableItems(), // first req
  });
  const { data: weapons } = useQuery({
    queryKey: ["cache_riven_weapons"],
    queryFn: () => api.cache.getRivenWeapons(),   // second req, even if not needed
  });
  // ...
});

so if in table rendering 100 items, there is 200 API calls

• saved 50% of loading speed

5. Lazy-load FinancialReport, load only on button click.

• saved 20-30ms

prettier made some linefarming, thanks for that
