chore (examples): update e2e example matchers

[YOU54F]

Rectifies a few failures in provider verifications for the e2e example projects

1. Few tests would fail if they got an array with more than 1 item in, despite all objects matching the same shape, so wrapped in an eachLike
2. Set auth header on request to POST /animals on consumer side

Also added a cookie trail regarding 2 defects which were already raised, and present in our examples.

#884
#662

Failures on verification don't fail the test builds for the e2e and v3/e2e projects as enablePending: true
