Fix express middleware and dev script loading mocks

[kasperpeulen]

The following PR caused 2 regressions:
#1066

Test Plan

1. The middleware is now loaded before the dev server starts. You can test this by running npm run dev and go to localhost:3000/login/ and see that it redirects to localhost:300/login/ now.

2. The mocks of index.ts are now loaded correctly. You can test this by going to npm run dev and see the message 🔶 Mock server installed in the console.

File	Description
server/index.ts	Moved the Vite dev server and production middleware block from immediately after app creation to after all other middleware (HTTPS redirect, trailing slash removal, compression, helmet, rate limiting, etc.), ensuring proper middleware execution order
package.json	Updated dev and dev:no-mocks scripts to run index.ts instead of server/index.ts, making them consistent with the start scripts and ensuring mocks are loaded before the server starts
