fix(preferences): default snapshot_threshold to 20 when unset

@krlvi I just hardcoded the default threshold amount in the frontend, but there’s the same hardcoded default value in Rust.
Is there a good way to bind these defaults and use a single source?

pub fn snapshot_lines_threshold(&self) -> usize {
    self.snapshot_lines_threshold.unwrap_or(20)
}

the app doesnt do this anymore so this can be removed from the UI entirely

[PavelLaptev]

The branch was corrupted and is in a weird state now. I'll leave it unchanged so we can investigate the issue later. I'll create another PR for this.

@PavelLaptev Please keep a copy of the folder around if still possible 😅, it's probably something to investigate.

[PavelLaptev]

@Byron yep. I wouldn't remove the branch :-)

Great, thanks, let's see what we can sort out in office then.
