Skip setup step 4 (host/port) when override vars are set

- Modified setup/2.post.ts to check for WG_HOST and WG_CLIENT_PORT overrides
- If both overrides are set, auto-populate host/port and mark setup as complete
- Updated setup/2.vue to check setup status after user creation and redirect appropriately
- Modified setup middleware to allow access to success page during setup
- Setup now completes after step 2 when host/port are provided via environment variables
