refactor: merge scripts/test/ into tests/verification/

Move 21 standalone verification scripts from scripts/test/ to
tests/verification/. These are run-manually scripts that hit live
services (not pytest suites). Consolidates all test-related files
under tests/ with clear separation:
- tests/cli/, tests/unit/, tests/integration/, etc. = pytest suites
- tests/verification/ = standalone verification scripts

tests/verification/verify_gpu_deployment.sh
