Validations against path traversal

[christopherholland-workday]

Add validations to ensure users are not navigating to disallowed locations in the filesystem -> Add a new validator to check for path traversals, URL encodings, absolute paths, etc

Additional:

• update/move tests so that they are discoverable (I don't think they were being ran as part of pnpm test previously)
• add eslint ignore for no-control-regex so that we can create a regex to check for control characters in the validator
