Use toUriString for paths in work-dir and FilesEx error messages (#7075)

Paths backed by non-default filesystems (e.g. S3, Azure) render as
opaque provider objects when interpolated directly into a GString.
Wrap them with toUriString so diagnostic messages show a usable
URI in the work-dir abort and in FilesEx permission/modify-time
failure logs.
