fix: attach images immediately + upgrade image prompts to v2

Browse Source 
Two fixes:

1. Image attachment: moved set_post_thumbnail() and Image B post meta
   into generate_and_attach_images() so they persist immediately after
   each image generates. Previously the caller set them after both images
   completed — if the process timed out (common with GPT-5 Image at
   ~30s/image), the featured image was never attached and Image B was
   never attempted.

2. Image prompts: replaced FLUX.1-optimized rewriter system prompt and
   90s infomercial style suffix with prompts optimized for Gemini Flash
   Image and GPT-5 Image. New style: premium scientific lifestyle
   photography with golds/teals color grading. Includes one-time migration
   to update stored style suffix.

Also logs when Image B is skipped due to missing source data (previously
silent), helping diagnose why some posts only get one image.
