/**
 * @function dateFromUUIDv7
 * @description Extracts the timestamp from a UUIDv7 string or Buffer and converts it to multiple date formats.
 *
 * Validates the input as a UUID, checks that it is version 7, and then
 * extracts the 48-bit timestamp from the first 12 hex digits. Returns an object containing
 * the timestamp in ISO string format, Unix epoch milliseconds, and UTC string format.
 * If the input is not a valid UUIDv7, returns `undefined`.
 *
 * @param {string | Buffer} uuid - The UUIDv7 as a string or Buffer.
 * @returns {DateFromUUIDv7} An object with `dateToIsoString`, `dateUnixEpoch`, and `dateToUTCString` properties, or `undefined` if invalid.
 *
 * @example
 * // Returns date object with multiple formats
 * dateFromUUIDv7('018fd8f9-8c00-7a4c-8a47-1a6d4b90f3a1');
 * // {
 * //   dateToIsoString: '2024-11-21T10:30:45.000Z',
 * //   dateUnixEpoch: 1732186245000,
 * //   dateToUTCString: 'Thu, 21 Nov 2024 10:30:45 GMT'
 * // }
 *
 * @example
 * // Returns undefined for invalid UUID
 * dateFromUUIDv7('not-a-uuid');
