/**
 * Detect the country dialing code from a phone number string that has
 * no separator between code and subscriber number.
 *
 * Uses a longest-prefix-match against every known E.164 country code
 * in the Eufemia countries list.
 *
 * @param value  A phone number string beginning with "+" or "00" (e.g. "+4712345678" or "004712345678").
 * @returns      An object with `countryCode` (e.g. "+47" or "+1-684" for
 *               dashed codes) and `phoneNumber` (e.g. "12345678"), or
 *               `undefined` when no known code could be detected.
 *
 * @example
 * detectCountryCode('+4712345678')
 * // => { countryCode: '+47', phoneNumber: '12345678' }
 *
 * detectCountryCode('004712345678')
 * // => { countryCode: '+47', phoneNumber: '12345678' }
 *
 * detectCountryCode('+16841234567')
 * // => { countryCode: '+1-684', phoneNumber: '1234567' }
 *
 * detectCountryCode('+hello')
 * // => undefined
