chore(server): standardize server db names and columns (#7674 )

feat(component): add animations to modal (#7474 )
Add opening and closing animations to modal. The usage of conditional rendering as shown below is not recommended: ``` open ? ( <Modal open={open} ... /> ) : null, ``` When the modal is closed, it gets removed from the DOM instantly without running any exit animations that might be defined in the Modal component.
