Settings Rework

* Add JSON string configuration field to RGBController to store device-specific configurations
    * This JSON string holds both configuration and schema
    * Add settings schema tracking to SettingsManager
    * Implement dynamic settings widget that generates a settings UI based on a JSON schema
    * Implement SettingsManager callback for notifying of settings changes and settings schema updates
    * Always enable Entire Device zone option and use it to enable Edit Device
    * Rename SaveSizes to SaveConfiguration in ProfileManager and Sizes.json to Configuration.json
    * Add zone flag for indicating that a zone's geometry may change, informing profile manager to ignore this check
    * Remove Theme setting and Theme Manager, as this didn't work on most setups anyways and Qt6 has proper Windows dark theming
