fix: show load widget inputs in media dropdown (#9670)

Main targeted, built on
https://github.com/Comfy-Org/ComfyUI_frontend/pull/9551

## Summary

Fix Load Image/Load Video input dropdown tabs not showing available
input assets in Vue node select dropdown.

## Changes

- **What**: Keep combo widget `options` object identity while exposing
dynamic `values` for cloud/remote combos.
- **What**: Remove temporary debug logging and restore clearer dropdown
filter branching.
- **What**: Remove stale `searcher`/`updateKey` prop plumbing in
dropdown menu/actions and update related tests.

## Review Focus

Verify `Load Image` / `Load Video` Inputs tab behavior and confirm
cloud/remote combo option values still update correctly.
