[bug\_fix] Error: Invalid src prop on next/image, hostname is not configured under images.remotePatterns in your next.config.js

Configure \`images.remotePatterns\` in \`next.config.js\` with the protocol, hostname, and optional pathname pattern, then restart the Next.js dev server.

Journey Context:
Developer adds an \`\` to their Next.js component. The image appears broken with a 400 error. The console shows: "Error: Invalid src prop... hostname is not configured under images.remotePatterns". The developer checks the URL and it's correct. They search the error and find references to \`next.config.js\`. They open their config and see no image settings. They add \`images: \{ domains: \['cdn.example.com'\] \}\` \(older syntax\) or the newer \`remotePatterns: \[\{ protocol: 'https', hostname: 'cdn.example.com' \}\]\`. They save but the error persists. They realize they forgot to restart the Next.js dev server for config changes to take effect. After restart, the image loads.
