Internal Function for Core BrAPI GET Calls

Fetches data from an API endpoint, handles pagination by retrieving all pages, and consolidates the results into a single data frame.

Usage

brapi_get_call(call_url, nested = TRUE)

call_url: Character string specifying the base URL of the API endpoint to request.
nested: Logical value indicating whether to flatten nested lists in the JSON responses. Defaults to TRUE.

A list containing the consolidated data and associated metadata from the API response.

This function performs the following steps:

Fetches the first page synchronously to determine the total number of pages.
If multiple pages exist, it asynchronously fetches the remaining pages using get_async_pages().
Consolidates the data from all pages into a single data frame.
Updates global state variables with pagination information.

It relies on global variables from qbms_globals to manage state and configuration.
