/**
 * Checks if a string is a valid representation of a CANopen PDO mapping entry.
 *
 * A valid entry is a 32-bit hexadecimal value representing:
 * - **Index** (16 bits)
 * - **Subindex** (8 bits)
 * - **Bit Length** (8 bits)
 *
 * It accepts formats with or without the '0x' prefix (e.g., "0x60400010" or "60400010").
 *
 * @param value The string to validate.
 * @returns `true` if the string follows the PDO mapping entry hex format, `false` otherwise.
 *
 * @example
 * isPdoMappingEntry('0x60400010'); // true
 * isPdoMappingEntry('60400010');   // true
 * isPdoMappingEntry('invalid');    // false
