fix: remove deprecated flux-1-dev model from Cloudflare image config

Browse Source 
FLUX.1 [dev] was removed from Cloudflare Workers AI in April 2026,
returning HTTP 400 "No route for that URI". This removes it from the
static model picker list and pricing calculations. Any saved setting
referencing flux-1-dev gracefully falls through to flux-1-schnell
via the null-coalesce in resolve_model().
