Method fetchAllByCount

frontend/src/api.js:120–144

* Fetch all pages for a paginated endpoint when you already know totalCount. * Builds page calls from totalCount and pageSize and aggregates all results. * - endpoint: path like "/api/channels/channels/" * - params: URLSearchParams for filters (will not be mutated) * - totalCount: total

(endpoint, params, totalCount, pageSize = 200)

   * Returns a flat array of results. Supports both array and {results, next} responses.
