fix(ci): resolve Round 4 compilation errors (7 issues)

Round 4 Fixes:
1. adapters/vnf-operator/tests/chaos/monitoring_chaos_test.go
   - Removed unused "net/http" import

2. adapters/vnf-operator/pkg/dms/o2_client_test.go:105
   - Fixed: cannot take address of http.Client{}.Timeout
   - Changed: &http.Client{}.Timeout → http.Client{}.Timeout

3. adapters/vnf-operator/pkg/translator/nephio_packager_test.go:33
   - Removed duplicate ValidatePackage method (already in nephio_packager.go)

4. adapters/vnf-operator/tests/e2e/monitoring_e2e_test.go:127
   - Fixed: declared and not used: promURL
   - Changed: promURL := → _ = (variable not used in test)

5. adapters/vnf-operator/tests/monitoring/prometheus_deployment_test.go:62
   - Fixed: TLSConfig redeclared
   - Renamed: TLSConfig → PrometheusTLSConfig (avoid conflict)

6. adapters/vnf-operator/pkg/controller/deployment_controller_test.go:119
   - Fixed: undefined: fixtures.eMBBVNFDeployment
   - Changed: fixtures.eMBBVNFDeployment() → fixtures.EMBBVNFDeployment()

7. adapters/vnf-operator/tests/performance/monitoring_performance_test.go:537
   - Fixed: TestMain using *testing.M instead of GinkgoTestingT
   - Added: &testing.T{} + os.Exit(m.Run())
   - Added: "os" import

All errors now resolved, code compiles successfully
