getPublicUrl() runs in the browser (called from client components rendering
recipe thumbnails), but read the plain STORAGE_PUBLIC_URL env var — never
inlined into the client bundle, so every browser fell back to the hardcoded
localhost:9000 default regardless of the real deployed storage domain,
tripping CSP img-src and mixed-content blocks in production. Added a
NEXT_PUBLIC_STORAGE_PUBLIC_URL build arg (Dockerfile, compose.prod.yml) wired
from the same STORAGE_PUBLIC_URL value, and getPublicUrl() now reads that.
Verified locally: building with a fake public storage domain set shows it
correctly inlined into the client JS chunk (previously only the localhost
fallback ever appeared there).
