Always enable static export and basePath

Simplify Next.js config by removing isProd/isStaticExport conditionals. Force output: "export", always enable trailingSlash and skipTrailingSlashRedirect, and set basePath/assetPrefix from NEXT_PUBLIC_BASE_PATH (default "/plugins-doc-site"). Also set images.unoptimized to true. These changes make the GitHub Pages / static export settings unconditional and simplify basePath resolution.
