That's a bit too many changes for one patch, it would be easier to
review with independent changes being split into separate patches

This setting should use the SettingValue::Clamped & the setLimit method
to prevent the interval to be 0

To the extent of what's possible, I'd like to keep settings created
where they are used

CF remark about the Clamped setting. Also, the math to convert the value
to milliseconds probably doesn't belong here, let's keep in in minutes
except for the call to setInterval

The point of one of the previous commit was to avoid exposing this, and
only export the changes as a signal. I don't think we need to be
actively querying for the project name, but rather let the UI connect to
the projectUpdated signal (which might need a better name, since it's
not a project update)

I don't think we need to expose the project path

Same remark about exposing the project path.
This might be an issue with the recent projects list, which is in an
external class. We could consider merging RecentProject & Project, but
that seems a bit weird

If you don't have an instance yet (which you don't, since you are in the
constructor) how can the signal be connected?
