/**
 * Prepares request payload for Dive API (v3 / v3.1 / v4) based on submitted capture data.
 *
 * Builds a normalized request object:
 * - extracts base64 images (front, back/second, face)
 * - prepares multi-capture images if available
 * - parses metadata
 * - adjusts payload structure depending on API version
 *
 * @template P - Additional custom payload fields to be merged into the request
 *
 * @param params - Parameters object
 * @param params.data - Raw data collected from the results of the IDVC capture flow
 * @param params.payload - Optional custom fields to extend the request payload
 * @param params.versionAPI - Target Dive API version (`'3' | '3.1' | '4'`)
 *
 * @returns Promise resolving to a prepared Dive API request object
 * compatible with the specified API version and extended with custom payload fields
