cf-removal: delete Cloudflare Workers AI provider files + tests
Drops the four CF provider classes and their two test files. The OpenRouter AI Gateway path is unaffected — it reads prautoblogger_ai_gateway_base_url via class-open-router-config.php directly, with no dependency on the CF support class. Leaves class-cost-tracker.php line 165 'cloudflare-workers-ai' label intact for historical log integrity. Part of v0.10.0 (removing CF Workers AI as image provider). See convo/prautoblogger/threads/2026-04-cloudflare-workers-ai-removal/.
