Replaces Cloudflare Workers AI (FLUX.1 schnell) as the default image provider with OpenRouter, which offers FLUX.2 Pro, Seedream 3.0, Gemini Flash Image, and GPT Image 1 at comparable or better pricing. - New provider class (3-file split: provider, pricing, support) reuses the existing OpenRouter API key and Cloudflare AI Gateway - Admin settings: new Image Provider dropdown (openrouter/cloudflare), model picker shows all available image models from both providers - Image pipeline auto-selects the configured provider at construction - Cost logging now uses actual model name instead of hardcoded flux-1-schnell - Default model changed to black-forest-labs/flux-2-pro ($0.03/image) - Unit tests for pricing resolution and provider response parsing Cost impact: FLUX.2 Pro at $0.03/image vs schnell at $0.0007/image — ~43x more expensive per image, but dramatically better quality. At 2 images/article × 1 article/day = ~$1.80/month. Seedream 3.0 ($0.003) available as a budget alternative. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
