/**
 * Pages through an offset-paginated data source, accumulating every item until `total` has been reached.
 * Use when a caller genuinely needs the full set rather than a single page — for example, populating a
 * dropdown of every configured language. Returns the same `{ data: { items, total } }` shape as a
 * single-page fetch, or `{ error }` if any page fails.
 *
 * If the server reports a higher `total` than it actually delivers — i.e. an empty page is returned
 * before `allItems.length` reaches `total` — the function fails with an error rather than silently
 * truncating, since a partial "fetch all" result would mislead the caller.
 * @param {UmbOffsetPageFetcher} fetchPage - Called once per page with the current `skip` and `take`.
 * @param {number} take - Page size used for every request. Must be a positive finite number.
 * @returns {Promise} A promise resolving to all items, or the first error encountered.
 * @throws {RangeError} If `take` is not a positive finite number.
