feat: enableHorizontalInfographics config flag — vertical-only by default

Adds Sanity pipelineConfig toggle to control horizontal (16:9) generation.
Default: false (vertical only). Halves Imagen API calls and generation time.
- Schema: enableHorizontalInfographics boolean on pipelineConfig singleton
- Type: enableHorizontalInfographics?: boolean on PipelineConfig
- gemini-infographics.ts: skipHorizontal option on generateFromScenePrompts
- check-research: reads config, passes to generator, adjusts total count
