[GUI] Move dialog settings button and control ID range

[Hitcher]

Description

Moves the range of negative IDs used for dialog settings to avoid overlapping with positive IDs used for buttons.
Button start changed from -100 to -200.
Control start changed from -80 to -180.

Motivation and context

Fixes #25125

How has this been tested?

Tested on Windows using https://mirrors.kodi.tv/test-builds/windows/win64/KodiSetup-20240506-a1c6d8ec-dialog_settings_id_range-x64.exe

What is the effect on users?

Screenshots (if appropriate):

Previous problem:

The number of settings in this addon exceed 80 so they use positive numbers which then clash with the button IDs.

After fix:





No ID clashes.
