feat(ui): add collapsible section for inventory information with toggle animation

- Wrap inventory information table in Bootstrap collapse component
- Add toggle button with chevron icon indicating collapse state
- Implement JavaScript to animate chevron icon on collapse/expand
- Set inventory information to be collapsed by default for cleaner UI

This change improves the user interface by reducing clutter on the inventory detail page, allowing users to focus on the most important information first and expand additional details as needed.
