feat: add getV4MultiAccountTransactionsInfiniteQueryOptions

[n3ps]

Explanation

This PR adds a new getV4MultiAccountTransactionsInfiniteQueryOptions method to AccountsApiClient that is designed specifically for useInfiniteQuery consumers:

• Stable query key: Excludes pagination params (cursor/after/before) from the query key so it remains stable across all pages. Only filter/sort params that affect which data is returned are included.
• Runtime pagination via pageParam: The queryFn accepts pageParam (provided by React Query) and maps it to the cursor API parameter, rather than closing over a fixed cursor value.

Extension consumption:

const base = apiClient.accounts.getV4MultiAccountTransactionsInfiniteQueryOptions({
  accountAddresses: ['eip155:0:0xabc...'],
  networks: ['eip155:1', 'eip155:137'],
  includeTxMetadata: true,
});

useInfiniteQuery({
  ...base,
  select: myCustomTransform,
  enabled: someCondition,
  refetchInterval: 15_000,
});
