Review Comment:
Done in aaee1a1. The helper converts to milliseconds, checks the result is
nonnegative and raises `ValueError("data-token.expiration-safe-time must not be
negative, got ...")`. PVFS reads the window once in `__init__`, so a typed
negative value fails at construction instead of on the first storage access.
Regressions: `test_negative_window_is_rejected` (RESTTokenFileIO) and
`PVFSTokenWindowTest.test_negative_window_is_rejected_at_construction` (PVFS).
