VoiceOver does not announce the role or interactivity of task items, making them appear as static text: A11y_.NET MAUI SDKs_VoiceOver

## Issue Subcategory:
Interactive element or widget missing role

## User Experience:
Assistive technology gives no indication that the element is activatable. A clickable div announced as “group” leaves users unaware they can operate it

## Repro Steps:
Turn on VoiceOver > Open Maui sample template app in Mac > Task Collection list > Navigate to any task > Observe the issue:

## Actual Result:
VoiceOver announces only the task name and does not indicate that the item is interactive. The task can still be activated using Control + Option + Space.

## Expected Result:
VoiceOver should announce the appropriate role and indicate that the task item is interactive (for example, button, link, list item with actionable state, or another suitable control type), so users understand that the item can be activated.

## How to Fix:
Use native HTML elements (``, ``, ``, etc.) whenever possible. For custom controls, add the appropriate ARIA role (e.g., `role="button"`, `role="tab"`, `role="switch"`, etc.). Verify the role against the intended UI pattern

Start with the .NET MAUI sample template app's Task Collection list on Mac and reproduce the issue using VoiceOver. Trace the task item's control definition and accessibility semantics; done when VoiceOver announces an appropriate role and that the item is actionable, while activation still works.
