[feat] integrate asset browser with widget system (#5629)

## Summary

Add asset browser dialog integration for combo widgets with full
animation support and proper state management.

(Thank you Claude from saving me me from merge conflict hell on this
one.)

## Changes

- Widget integration: combo widgets now use AssetBrowserModal for
eligible asset types
- Dialog animations: added animateHide() for smooth close transitions
- Async operations: proper sequencing of widget updates and dialog
animations
- Service layer: added getAssetsForNodeType() and getAssetDetails()
methods
- Type safety: comprehensive TypeScript types and error handling
- Test coverage: unit tests for all new functionality
- Bonus: fixed the hardcoded labels in AssetFilterBar

Widget behavior:
- Shows asset browser button for eligible widgets when asset API enabled
- Handles asset selection with proper callback sequencing
- Maintains widget value updates and litegraph notification

## Review Focus

I will call out some stuff inline.
