style(ui): refine file list styling and remove transform animations

- Reduce font sizes for names and folders for better visual hierarchy
- Remove scale and translate transforms on media cards during hover/selection
- Adjust line heights and max heights to accommodate new font sizes
- Simplify card transitions to box-shadow only for smoother interactions
