v1.9.17: fix explore card — chain GET STATUS + GET RESPONSE inside SCP80

Key fix: re-add chained C0000000 (GET RESPONSE Le=00) in paginate() so the
full GP APDU inside SCP80 is 80F2<p1>p2024F0000C0000000, matching the
working tool. The card's SCP80 layer executes both commands internally
(GET STATUS → 61XX → GET RESPONSE) and puts the final 9000 + data in
the PoR.

Also: server logging improvements (RAM RESPONSE-PACKET label, no truncation
of FETCH/PoR hex), docs for /api/ram-install endpoint, minor test fix.
