feat(intern-decision): decision seat swapped to h2o-lightning-4b on fv-ml1 GPU 1; eval seat down

The :8033 seat now serves h2oai/h2o-lightning-4b @ b43f759b on vLLM 0.30.0 with
byte-pinned KV (4.48 GiB, 135,558 tokens) behind services/h2o-decision-front:
32k refuse-not-trim admission, the seat's bearer token, and /decide +
/decide/shared translated onto /v1/systemone for albok-nemi's judge. URL, port,
token and stack name are unchanged. INC down 13:08:18, h2o healthy 13:11:27.

Post-checks on the live seat: /health at the pinned revision; JevBench public
205/231 (= bench); 422 over the cap; 16q at the cap warm 2.0-2.16 s; seat peak
16,164 MiB under 4 concurrent 16q x 32k calls against a 16,847 budget.

compose.inc.yaml + rollback-to-inc.sh restore Intern-Decision-4B in one step.
The temporary GPU 3 eval seat (stacks/h2o-eval) is down.

 h2o-lightning-4b @ b43f759b behind `services/h2o-decision-front` (copied into `conf/front/`), for albok-dev's
 re-validation of Nemi's sensitivity judge before the GPU 1 cutover (Prime 2026-10-12 via brokkr). **Remove right after
 the cutover:** GPU 3 is for transient work only (Scriberr and MIA use it).
