Yahoo Ads Adapter: fix user.ext merging to prevent nested structure (#14261)

Fixes a bug where ortb2.user.ext properties were being nested as user.ext.ext
instead of being merged into user.ext, causing malformed OpenRTB requests.

The issue manifested starting with Prebid.js v9.53.2 when PR #13679 backported
the userId aliasing feature that populates ortb2.user.ext.eids alongside
bid.userIdAsEids. This exposed a latent bug in the appendFirstPartyData function
that has existed since the adapter's initial release in v5.18.0.

Changes:
- Modified appendFirstPartyData to merge ortb2.user.ext properties using spread operator
- Updated test expectations to verify correct merged behavior instead of nested structure
