feat(editor): manual mesh renderer setup + asset hover info card

Mesh Renderer was missing from the Add Component menu and its model reference was read-only, so a mesh could only be attached by loading a saved scene. Add it to the menu (Unity Add Component semantics) and give the block a UE-Details-style asset slot: a dropdown listing all model files under assets/, selecting applies LoadModel (cache deduped). Asset browser files now show a UE Content Browser style hover card: kind, size, modified time, and loaded state (new AssetCache::Contains query, read-only -- hovering never triggers loading). Fix latent FATALs unlocked by manual assignment: AssetCache::Get aborts on invalid handles, so rendering, animation sampling, and mesh collider build now guard mr.model.Valid() before calling it.
