 * Converts microcredits to credits for display purposes.

 * The backend stores credit balances in microcredits (1 credit = 10,000 microcredits)
 * to avoid floating point precision issues when performing calculations.
 * This function converts the microcredits back to the user-facing credit amount.
 *
 * @param microcredits - The balance in microcredits from the backend
 * @returns The balance in credits (typically displayed with 4 decimal places)
 *
 * @example
 * formatCreditsBalance(50000) // returns 5.0000 (credits)
 * formatCreditsBalance(12345) // returns 1.2345 (credits)
