Current Behavior:

When the keyboard opens in the Add Task bottom sheet, the entire sheet shifts upward to accommodate the keyboard. This causes the following issues:

• The bottom sheet pushes too far up, potentially hiding important UI elements
• Users cannot see the full form while typing
• Poor user experience when filling out multiple fields

Expected Behavior:

• The bottom sheet should move up only slightly when the keyboard opens
• The sheet should maintain a maximum height that leaves some space from the top of the screen
• Users should be able to scroll through the form fields comfortably while the keyboard is visible
• The header (Cancel/Title/Save buttons) should remain visible and accessible at all times
