DateNavigatorItemProperties extends dxButtonGroupOptions, so no point of including dxButtonGroupOptions here

[Copilot]

Pull request overview

This PR refactors the Scheduler TypeScript declarations to align dxScheduler with the Properties-based typing pattern and to reuse canonical Properties/Item types from related widgets (ButtonGroup/Toolbar). It also updates the Vue Scheduler wrapper typings accordingly.

Changes:

• Updated dxScheduler to extend Widget<DevExpress.ui.dxScheduler.Properties> instead of Widget<dxSchedulerOptions>.
• Refactored Scheduler-related composite types (e.g., DateNavigatorItemProperties, toolbar item base types) to use dxButtonGroup.Properties/dxButtonGroup.Item and dxToolbar.Item.
• Updated the Vue wrapper Scheduler component prop typings (notably the options prop unions).

• packages/devextreme-vue/src/scheduler.ts is generated output (see packages/devextreme-vue/project.json target generate-components, which outputs {projectRoot}/src/**/*). Direct edits here are likely to be overwritten on regeneration; the change should be made in the Vue wrapper generator/metadata and then nx generate-components devextreme-vue (or nx run devextreme-vue:regenerate) should be run to update src/.

• dxButtonGroupOptions was removed from the devextreme/ui/button_group imports, but it is still needed if options props accept values typed as dxButtonGroupOptions. Without it, the remaining union uses Record<string, any>, and a dxButtonGroupOptions-typed variable is not assignable to Record<string, any> because it lacks an index signature (TypeScript will report an error).

Created a test script:

const options: dxButtonGroupOptions = {}
let accepted: DateNavigatorItemProperties | Record<string, any> = options;
accepted = options;

No type errors.
