fix: replace non-word chars in uploaded filenames

Storage maintains a list of allowed characters, which excludes some
characters used automatically by OSes for naming files (e.g., Mac
default screenshot naming). To preempt errors, replace any characters
that aren't alphanumerics, underscores, hyphens, or periods with
underscores.
