Fix Python type errors: remove stale PermissionDecision fields

PermissionDecision no longer has rules/feedback/message/path fields
in the new permission vocabulary. Clean up PermissionRequestResult
dataclass and client.py payload construction to match.

Passes ty check, ruff lint, and all E2E tests.
