reject profile names that resolve outside data-dir

The character check allowed "." and "..", which are made entirely of allowed
characters and still walk out of the directory, so the traversal guard only
stopped the cases containing a separator. Reject both by name and check the
resolved path against the profile root as well, since the character set
constrains the characters rather than where they point.

Also drop the MouseUtils and KeyboardUtils built in run_account and never
used, RewardsTaskUtils builds its own, along with the two imports that
leaves unused, and say "lowercased" in the no-source warning, which is what
the code returns.
