refactor molecule components to use .withProps() subcomponents and extract inline code

- Add UnstyledButton listItem theme variant to replace inline style for border-radius
- Extract subcomponent constants with .withProps() across all molecules
- Replace raw <span /> with Mantine <Flex /> in ResourcePreviewPanel
- Extract inline template literals and expressions to named functions
