Remove rounded corners from dialogs and task input fields

Update DialogContent component to remove rounded corners by setting `rounded-none` class. Modify TaskFormInline component in Tasks.tsx to remove `borderRadius: '6px'` and set `borderRadius: '0px'` for various input elements and buttons. Also, change the default value of the 'assignedTo' input field from 'admin' to an empty string.
