Fix/routine builder modal position

[Sonalis1299]

📌 Description

Fixed the modal positioning issue in the Routine Builder section where the “Create New Task” and “Save Routine” modals were appearing relative to the scrollable webpage instead of the visible viewport.

The issue was caused by the parent container animation class affecting the modal’s fixed positioning behavior.
