## Summary of the Pull Request
Adds a new Hosts File Editor setting “No leading spaces” that prevents
prepending spaces to active lines when saving the hosts file (when any
entry is disabled). Default is Off to preserve current behavior.

`NoLeadingSpaces`
- `src/modules/Hosts/HostsUILib/Settings/IUserSettings.cs`: add
`NoLeadingSpaces`

- Writer change:

with `anyDisabled && !_userSettings.NoLeadingSpaces`

`NoLeadingSpaces_Disabled_RemovesIndent`
Backward compatibility: default Off, current formatting unchanged unless
the user enables the option.
## Validation Steps Performed
- Automated: `HostsEditor.UnitTests` including
`NoLeadingSpaces_Disabled_RemovesIndent` passing.
- Manual:
1. Run PowerToys (runner) as Admin.
2. Settings → Hosts File Editor → enable “No leading spaces”.
3. In editor, add active `127.0.0.10 example1` and disabled
`127.0.0.11 example2`; Save.
4. Open `C:\Windows\System32\drivers\etc\hosts` in Notepad.
- ON: active line starts at column 0; disabled is `# 127...`.
- OFF: active line begins with two spaces when a disabled entry
exists.
