Directly include Settings struct for the server (#16042)

## Summary

This PR refactors the `RuffSettings` struct to directly include the
resolved `Settings` instead of including the specific fields from it.
The server utilizes a lot of it already, so it makes sense to just
include the entire struct for simplicity.

### `Deref`

I implemented `Deref` on `RuffSettings` to return the `Settings` because
`RuffSettings` is now basically a wrapper around it with the config path
as the other field. This path field is only used for debugging
("printDebugInformation" command).
