/**
 * A safe pattern matcher that uses glob-style patterns instead of regex.
 * This eliminates regex injection vulnerabilities while providing
 * sufficient flexibility for matching users and issuers.
 *
 * Supported patterns:
 * - * matches zero or more characters
 * - ? matches exactly one character
 * - All other characters match literally
 *
 * Examples:
 * - *@example.com matches any email at example.com
 * - user-? matches user-1, user-a, etc.
 * - https://*.auth.com matches any subdomain of auth.com
