Recipe count and storage usage shared the monthly user_usage bucket with
AI calls, so both incorrectly reset every month even though nothing was
deleted. Only AI calls should be monthly.
Recipe count and storage are now derived live from real data (recipes,
recipe/review photos, avatar) instead of a counter — deleting a photo or
recipe is itself the "decrement", no extra wiring needed. Storage size is
tracked per-row (recipePhotos.sizeMb, ratings.photoSizeMb, users.avatarSizeMb)
and threaded through presign -> upload -> save.
Also fixes avatar removal silently no-oping (client sent a field the PATCH
schema didn't recognize).

Full list of the audit's confirmed findings and their fixes:
- Stored XSS via unescaped JSON-LD on the public recipe page
(app/r/[id]/page.tsx) — escape < before injecting.
- CSP allowed unsafe-eval in production — now dev-only (Next prod
never eval()s; only its HMR does).
- avatarUrl accepted any URL with no ownership check — now takes an
avatarKey issued by avatar-presign, validated server-side, same
pattern as recipe/review photos.
- No session revocation on password change/reset — both now revoke
other sessions (revokeOtherSessions: true, revokeSessionsOnPasswordReset).
- Rate-limit bypass via spoofable X-Forwarded-For — take the last
(proxy-appended) hop instead of the first (client-supplied) one,
matching the single-Traefik-hop topology.
- Webhook signing secrets stored plaintext — now AES-256-GCM
encrypted like every other secret in this app, with a legacy-
plaintext fallback for pre-existing rows (bare hex has no ":", our
ciphertext format always does).
- Better Auth's own rate limiter defaulted to in-memory storage,
ineffective across replicas — now backed by the same Redis as
lib/rate-limit.ts (secondaryStorage), with storeSessionInDatabase
explicit so session storage itself doesn't move as a side effect.
- Presigned upload URLs didn't bind the declared file size to the
actual upload, letting a client under-declare size (and quota
charge) then PUT an arbitrarily large object — switched to S3
presigned POST with a signed content-length-range condition,
enforced by the storage server itself.
- generateMetadata() on the recipe page skipped the visibility
filter the page body uses, leaking a private recipe's title via
<title> to any signed-in user with the id.
- Block/unblock had no rate limit, unlike follow/unfollow.
- AI quota was charged even when a user's own BYOK key was used
(their own credentials/billing) — added an isByok flag through
the config-resolution chain and skip the charge when set. Also
wired BYOK into generate/generate-from-idea/translate/import-url,
which never looked it up at all before.

New users get a Gravatar-backed avatar automatically (computed from email
at signup); users can upload a custom photo instead via Settings, or
revert to the Gravatar/initials fallback. avatarUrl stays the single
resolved value (custom photo, OAuth photo, or precomputed Gravatar URL)
so every existing avatar-rendering spot across the app needs zero changes.
- users.hasCustomAvatar tracks whether avatarUrl is a real upload vs a
computed Gravatar fallback, so "remove photo" knows what to revert to.
- New /api/v1/upload/avatar-presign route (session-scoped, generic —
the existing recipe-photo presign route required a recipeId).
- CSP img-src needed www.gravatar.com added, or every browser blocks
the fallback avatar outright.
- Settings page now reads avatarUrl from a fresh DB query instead of
Better Auth's session object — the session cookie cache (5 min TTL)
was serving a stale image right after upload, showing the initials
fallback until the cache happened to expire.
Verified locally: signup auto-sets a Gravatar URL, upload persists
across reload, remove correctly reverts to Gravatar/initials.
