Address PR #21 review: drop redundant SSR write + stale scenarios.json entry

- app.py: remove the `os.environ["GRADIO_SSR_MODE"] = "false"` module-level
write I added during conflict resolution. The latest main commit
(8c1267a, "Patch Gradio schema crash") explicitly removed it as
"the ineffective GRADIO_SSR_MODE env var workaround" — the
schema-patch monkeypatch on lines 28–33 is the real fix and is
preserved. Reintroducing the env-var line was a regression vs main.

- site/public/scenarios.json: drop `artofwar-decoy-sacrifice` (now
archived under openra_bench/scenarios/packs/_archive/). Filtered
in-place since regenerating via site/generate.py needs pydantic
+ PIL which aren't installed in this checkout. 209 → 208 entries.
