New UI needs to populate the default field for type on System -> Tunable
In addition, the quicklink header says System / Tunable, while everywhere else says Tunables. The Value field is also large, it's 2 lines while the Variable and Comment field are one. Looks out of place ;)
Currently, if the user leaves the type field empty, it defaults to 'loader' like the legacy UI does. But the user should either be:
- Prompted to select a type themselves
- The field not be empty and show loader instead, as that is the default.
