fix: correct web service port mapping for development mode

- Changed web service port from 3001:80 to 3000:3000
- This matches the Vite development server port in the development target
- Fixes UI accessibility issue where Vite runs on port 3000 but was mapped to 3001

The issue was that docker-compose.dev.yml was using production port mapping
(3001:80 for nginx) but the development target uses Vite on port 3000.

Now the UI is accessible at http://localhost:3000 as expected.
