Add image-gen module: Spring AI ImageModel options on the wire, a moderation gate, and safe storage of generated images in MinIO (sniffed content type, byte and pixel caps, server-chosen keys, capped URL fetcher); per-provider cost table dated 2026-10-28. ImageModel and ModerationModel are hand-written fakes; MinIO is real via Testcontainers; no image provider called.

# Key construction
200 puts of identical bytes -> 200 distinct ids (a content hash would give 1)

id '0123456789abcdef0123456789abcde/' -> bad-id: an image id is 32 lowercase hex characters
user-43 asks for user-42's id -> NoSuchKeyException (key is rebuilt under user-43/)
