docs: Remove Makefile section from E2E fixes documentation

The Makefile change was environment-specific for Colima and is not needed
when using Docker Desktop (which has Compose V2 plugin built-in).

Updated documentation to reflect 4 essential fixes instead of 5.

-## For Wadii
-
-All setup issues resolved! Here's what was wrong:
-
-1. **Deadlock** - Backend needed advisory locks
-2. **Network errors** - Tests were trying to reach production API
-3. **Docker compatibility** - Makefile needed auto-detection
-
-Tests now pass reliably at 10/10 (100%). You can run the standard command:
-```bash
-cd frontend
-make test opts="--grep @oss"
