Decoupled UI and data

[KamaleiZestri]

Type of Change

• New feature
• Bug fix
• Documentation update
• UI/UX improvement

Description

Problem: -config test.json -run does not function (only runs tweaks) due to $sync.form.Dispatcher.Invoke calls blocking until UI is loaded. This causes a race condition where features and install do not run.

Solution: This PR lays the groundwork for a fix rooted in running tweaks,features,installs, and toggles WITHOUT the UI having to be loaded.

What this PR Does: Following on from the Install tab UI rework that introduced $sync.selectedApps, this PR does the same for the other tabs with the following changes:

• Remove Get-WinUtilCheckBoxes.ps1 . No need to query UI anymore.
• Change any references to Get-WinUtilCheckBoxes.ps1 to now read from the $sync.selected variables
• Change Invoke-WPFSelectedAppsUpdate.ps1 into more generic Invoke-WPFSelectedCheckboxesUpdate that is called on any checkbox interaction in the UI to update the $sync.selected variables
• Seperate major Invoke-WPFPresets.ps1 functionality into data-focused Update-WinUtilSelections.ps1 and UI-focused Reset-WPFCheckBoxes.ps1
• Simplification of config.json output format. (its flat now).
