Fix Lakebase acceptance tests for backend changes (#4746)

## Summary
- Rename endpoint from `primary` to `custom` in
`postgres_endpoints/basic` test to avoid conflict with the auto-created
primary endpoint
- Add `enable_pg_native_login` to the mock server's project response to
match current backend behavior
- Update golden files

## Test plan
- [x] All 4 tests pass locally (both direct and terraform)
- [x] All 4 tests pass on AWS cloud (direct); terraform has pre-existing
provider issues unrelated to this PR
