Schema now defaults to tenant_${cameleer.tenant.id} (e.g. tenant_default,
tenant_acme) instead of public. Flyway create-schemas: true ensures the
schema is auto-created on first startup. CAMELEER_DB_SCHEMA env var still
available as override for feature branch isolation. Removed hardcoded
public schema from K8s base and main overlay.
