refactor: extract shouldUseAssetBrowser(), fix missing inputNameForBrowser, sanitize logs (#8867)

## Summary

Extract duplicated asset-browser eligibility guard into
`shouldUseAssetBrowser()`, fix a missing parameter bug, and sanitize a
log statement.

## Changes

- **What**: 
- DRY: Extract the repeated 3-condition guard (`isCloud &&
isUsingAssetAPI && isAssetBrowserEligible`) into
`assetService.shouldUseAssetBrowser()`, used by `widgetInputs.ts` and
`useComboWidget.ts`
- Bug fix: `createAssetBrowserWidget()` in `useComboWidget.ts` was
missing the `inputNameForBrowser` parameter, which could show wrong
assets for nodes with multiple model inputs
- Security: `createAssetWidget.ts` no longer logs the full raw asset
object on validation failure
- `WidgetSelect.vue` keeps an inline guard because it has a special
`widget.type === "asset"` fallback that must stay gated behind
`isUsingAssetAPI`

## Review Focus

- `shouldUseAssetBrowser()` correctly combines the three conditions that
were previously duplicated
- `WidgetSelect.vue` preserves exact behavioral equivalence (a widget
can have `type === "asset"` when the setting is off if a user toggles
the setting after creating asset widgets)

Fixes #8744
