fix(billing): add billing feature flags as Dockerfile build args

NEXT_PUBLIC_ENABLE_PERSONAL_ACCOUNT_BILLING and
NEXT_PUBLIC_ENABLE_TEAM_ACCOUNTS_BILLING must be set at build time
(ARG/ENV in Dockerfile + build args in docker-compose) because Next.js
bakes NEXT_PUBLIC_* into the bundle during 'next build'. Setting them
only as runtime environment vars has no effect.
