Tenant-specific OIDC: separate Zitadel projects per tenant

Each tenant config now includes oidcClientId. Auth composable reads
client ID from tenant config instead of hardcoded fallback. Dev tenant
uses restricted Zitadel project (role-check enabled, developer grant).
Added NODE_ENV=production to env files to fix --mode dev builds.
