CORs setup needed for Hono.js

[KyleAMathews]

Reference for when we add a Hono doc page:

app.use(
  "*",
  cors({
    origin: ["http://localhost:3000", "http://localhost:8787"],
    allowMethods: ["GET", "HEAD", "DELETE", "OPTIONS"],
    allowHeaders: [
      "Authorization",
      "Content-Type",
      "Accept",
      "Electric-Schema",
      "Electric-Up-To-Date",
      "Electric-Offset",
      "Electric-Handle",
    ],
    exposeHeaders: [
      // These are crucial for Electric SQL to work
      "Electric-Schema",
      "Electric-Up-To-Date",
      "Electric-Offset",
      "Electric-Handle",
    ],
    credentials: true,
  })
);
