funman300 739228efdb feat(host): capture unclaimed request bodies; record the consumable-apply wire
Milestone 2: the consumable-apply protocol is now LIVE_PROVEN.

Adds opt-in passthrough BODY logging (OPENFUT_FIFA17_LOG_PASSTHROUGH_BODY=1,
default off, capped at 512 bytes) because a body is what names an unknown
mutation's operands, while also being the one place a request could carry
something that should not reach a log. Staging probe only.

With it, one operator apply captured the whole thing:

    POST /ut/game/fifa17/item/resource/5001004
    {"apply":[{"id":100000003}]}

  source consumable : resource 5001004 (player contract, subtype 201) -- in the PATH
  target item(s)    : wire 100000003 (squad slot 0 GK, resourceId 200389) -- body apply[]
  verb              : POST

There is NO /apply endpoint, exactly as the static route work concluded. The
apply re-uses `ut/%s/item/resource`, which we already serve for GET (definition
lookup); the POST verb on that path is the mutation and nothing claimed it. This
is the wire form of the ApplyCardByRes task (id 0x0e), which is why the source is
a definition id rather than an instance id. `apply` is an array, so one resource
can name several targets.

Fail-closed verified: with the upstream dead the request 502s and Core is left
exactly unchanged -- coins 29,843,976, owned 1993, consumables 17, source card
still owned. No partial mutation.

NOT implemented: the response shape is unobserved and the EFFECT is unreversed.
Our catalog carries contract:7 for 5001004, documented as the matches granted,
but that is observed profile data (INFERRED), so no effect is written on it.

Bonus, caught by the same logging: the client really does request
`club/consumables/development`, which has no arm in
consumable_families_for_category and is served empty. Recorded, not guessed.

Host 120 lib tests, fmt clean.
