fix: configure Next.js to transpile @svg-maps ES modules

Add @svg-maps/world and @svg-maps/usa to transpilePackages array so Next.js can properly transpile these ES module packages for the server-side Node.js environment.

This fixes the "Unexpected token 'export'" error in know-your-world Validator when the server tries to load map data via dynamic import.
