Rule changes not getting saved when using the GUI to alter Papercut Service

[Pxtl]

Describe the bug

To Reproduce
Steps to reproduce the behavior:
For backwards compatibility with my old Incoming dir, I've installed it to
C:\ProgramData\Changemaker Studios\Papercut SMTP
and installed the client for all users to
C:\ProgramData\Changemaker Studios\Papercut SMTP Client
(had to manually create start menu shortcut for some reason but whatever)

I attempt to create a Rule in the GUI, and the changes are not propagated to
"C:\ProgramData\Changemaker Studios\Papercut SMTP\Papercut.SMTP.Service.Settings.json"

that file remains empty.

The documentation says:

Rule changes work the same way.
Configuration Files

Configuration is managed through a layered system:

Papercut.Service.Settings.json - User-editable settings that persist UI changes
    Located in the same directory as Papercut.Service.exe
   Contains configuration with comments outlining options
   Changes made via the Papercut UI are saved here automatically

Expected behavior
Changes made will appear in the Service

Screenshots
If applicable, add screenshots to help explain your problem.

Note that old messages are still present:

Found two issues here:

1. Docs were wrong — rules are never stored in the Settings.json file; they persist to rules.json next to the service exe. Readme corrected.
2. Real bug — when the service is online, the UI stopped publishing rule changes to it entirely, so new rules never reached the service. Fixed for the next release.

Workaround for now: rules save to rules.json in the client install dir on app exit — copy it next to the service exe and restart the service.
