I’m using Supabase with Resend, and I keep getting this error:

"Error: RESEND_API_KEY environment variable is not configured"

Please do the following:

1. Show me exactly how to configure the RESEND_API_KEY environment variable in Supabase project settings so it’s available to my function in production.
2. Show me how to configure the RESEND_API_KEY locally, either by:
   • Setting it in my terminal (export RESEND_API_KEY=your_actual_api_key), or
   • Creating a .env file with RESEND_API_KEY=your_actual_api_key.
3. Remind me to restart the local dev server or Supabase function after setting the variable.
4. Provide the corrected function code that:
   • Imports the latest Resend SDK using

     import { Resend } from 'npm:[email protected]';

   • Reads RESEND_API_KEY from process.env.
   • Throws a clear error if the key is missing.

Finally, give me steps to test the function after setting the key.
