[fix] Select Railway services when redeploying previews

[mmabrouk]

Context

Railway preview deploys started failing after setup with No deployment found for service. The deploy script checked Postgres but then ran a bare railway redeploy --yes, which depends on the CLI's currently linked service. The current Railway CLI exposes explicit --service selection and treats the old implicit service form as deprecated, so the bare redeploy can target a service with no deployment, such as gateway, before the script reaches Alembic or app deployment.

Changes

Redeploy calls now pass the intended service and environment directly.

Before:

railway service "$POSTGRES_SERVICE" >/dev/null && railway redeploy --yes

After:

railway service "$POSTGRES_SERVICE" >/dev/null && railway redeploy --service "$POSTGRES_SERVICE" --environment "$ENV_NAME" --yes

The same explicit selector is used for the image-based preview deploy helper and smoke-test auto-repair paths, so no path relies on mutable Railway CLI service state for redeploys.

Tests / notes

• bash -n hosting/railway/oss/scripts/deploy-from-images.sh hosting/railway/oss/scripts/deploy-services.sh hosting/railway/oss/scripts/smoke.sh
• git diff --check -- hosting/railway/oss/scripts/deploy-from-images.sh hosting/railway/oss/scripts/deploy-services.sh hosting/railway/oss/scripts/smoke.sh
• Verified the failing run failed before Alembic/API/web deploy at the bare redeploy step with Railway CLI 5.15.0.

📝 Walkthrough

Summary by CodeRabbit

• Chores
  • Improved deployment process consistency by ensuring services redeploy in the designated environment across all operations.

Walkthrough

Three Railway OSS hosting scripts are updated to pass --environment "$ENV_NAME" explicitly to every railway redeploy invocation: the generic helper in deploy-from-images.sh, the Postgres redeploy in deploy-services.sh, and the three auto-repair redeployments in smoke.sh.

Changes

Explicit Railway environment targeting for redeploys

Layer / File(s)	Summary
Add --environment to all redeploy invocations hosting/railway/oss/scripts/deploy-from-images.sh, hosting/railway/oss/scripts/deploy-services.sh, hosting/railway/oss/scripts/smoke.sh	redeploy_service_if_exists gains --service "$service" --environment "$ENV_NAME"; the Postgres redeploy gains --environment "$ENV_NAME" (and drops its separate --yes); each of the three repair_path redeployments in smoke.sh gains --environment "$ENV_NAME".
