fix(ide): capture multiple segments on base64 query path arguments (#754)

The endpoints `can-onboard` and `rulesets` rely on having a path parameter which is a base64 string. The problem is that this string may have `/` chars, thus making rocket unable to map the route.

The fix is matching against [multiple segments](https://rocket.rs/guide/v0.4/requests/#multiple-segments)
