fix(scenario): enforce scenarioChunkSizeLimit in CompileScenarioJSON

Browse Source 
The constant was declared and documented but never used, causing a
golangci-lint failure. Wire it into compileScenario() so oversized
chunks are rejected with a clear error rather than silently served
to the client (which discards them per FUN_11525c60 RE findings).
