fix: replace env_file with explicit env vars for cameleer-saas

Revert env_file approach — only pass the specific env vars the SaaS
app needs for its own database, identity, and tenant provisioning.
Organized into clear groups: Docker, SaaS database, Identity, and
Provisioning (passed to per-tenant servers).
