fix(egress): redact the per-bottle token in the now-active multi-tenant response log

Self-review of this PR: making `response()` run in the consolidated gateway
also activates its `LOG_FULL` `_log_response` call there — previously
unreachable, since the empty static config made `response()` return early. That
logger redacted with `os.environ`, which in multi-tenant mode does NOT hold the
bottle's per-request `/resolve` tokens (only the resolved `env` overlay does),
so a non-token-shaped provisioned secret appearing in a response could be logged
in the clear.

Thread the resolved per-flow `env` into `_log_request` / `_log_response` so the
LOG_FULL redaction scrubs the calling bottle's secrets. Adds a regression test
(a non-token-shaped `/resolve` secret, absent from os.environ, must not appear
in the response log) and updates the redaction-test helpers for the new arg.
