refactor: Remove dead code and stale references (#2238)

- Remove sh/e2e/aws-e2e.sh: dead backwards-compat wrapper with no
  references (superseded by unified e2e.sh --cloud aws)
- Remove getStatusDescription from commands/shared.ts: defined and
  tested but never called in production code
- Remove parseJsonRaw from packages/cli/src/shared/parse.ts: zero
  production usages (still available in packages/shared if needed)
- Update corresponding test files to remove dead code tests
- Bump CLI version to 0.14.4
