create and manage tasks in the calendar app

Feature describtion

When we create a "new calendar with task list" we cannot convert their tasks thats we have been created manually on calendar day view or week view (with tasks clicked by mouse) ==> to be converted to the nextcloud "Tasks" application.

(we appreciate that the same things to be done with the the default nextcloud calendar without task list)

Expected Solution

Make the "new Calendar with task list" to be convertable to the nextcloud "Tasks" application
(like "ticktick android app" calendar can be converted to task list and tickable)

(we appreciate that the same things to be done with the the default nextcloud calendar without task list)

Considred Alternatives

The alternate way is to avoid adding tasks manually everytime on tasks app however we should add them on calendar view directly without the headache of adding due date and time for every task?
(see the ticktick android app paradigm)
[[calendar view tasks <=converted to=> tickable tasks]]
when task is ticked on tasks is should be strikethrough on calendar view also and removed after the user permission.

The issue names no files, tests, or implementation entry points. Start by reviewing how tasks created in the calendar day and week views relate to the Nextcloud Tasks application. Done means calendar-created tasks can be converted and synchronized with tickable Tasks entries, including completion styling and removal behavior after user permission.
