fix(dropwizard-dedup): noise Content-Length, restore full header capture

Previous attempt stripped Vary + Content-Length from the captured
response header set to look like Spring's keploy-record output —
that broke linux replay too because keploy strict-compares the set
of response headers, not just values: dropwizard's Jetty actually
emits Vary + Content-Length on the wire, so a fixture that omits
them is "missing" a header from the live response and fails the
match across all 200 tests on both linux and docker.

Restores full header capture (Date, Content-Type, Vary, Content-
Length) and adds `header.Content-Length: []` to noise on top of
Date and Vary. That keeps the header set equal between fixture and
live response while letting docker-mode framing (chunked vs explicit
Content-Length) ignore the value drift that originally broke docker.

Reverts the `127.0.0.1` -> `localhost` host swap from the previous
attempt as well; it was unrelated to the docker failure (keploy
sends the recorded Host header verbatim) and only added churn.
