[Suggestion] Improve Asset Catalog Usability in Creator Hub

**Is your feature request related to a problem? Please describe.**
It's hard to find and manage assets in the Creator Hub due to limited filtering options, poor visibility, and lack of intuitive navigation.

**Describe the solution you'd like**

- Add filtering by asset type/category.
- Add collapsible/expandable categories.
- Display asset names under icons (not only on hover).
- Show preview on hover for 3D assets.
- Add "rectangle" mode to adjust asset's position (like Unity).
- Allow closing dropdowns with the Esc key.
- Include reset values option for components (like Unity's 3 dots).
- Show absolute position clearly.

Describe alternatives you've considered
Manual exploration of assets or dragging them into the scene to preview them (which is time-consuming).
