feat(notifications): add user follow defaults

[rebelchris]

Summary

• add user_follow to the default notification flags so new users inherit the existing subscribed behavior
• add user_follow to the strict notification flags schema so notification settings updates accept and persist the new preference

Key Decisions

• kept the change additive and limited to the existing notification flags mechanism instead of introducing new storage or API paths
• updated shared defaults and schema together so the new preference is both surfaced consistently and validated correctly

Closes ENG-1283

🍹 The Update (preview) for dailydotdev/api/prod (at 0182cf1) was successful.

✨ Neo Explanation

Routine deployment promoting commit `41c4bded` across all API services, workers, and cron jobs, with accompanying DB and ClickHouse migration jobs. ✅ Low Risk

This is a standard application deployment rolling the entire fleet from commit 50e660c0 to 41c4bded. Every deployment and cron job is updated solely to reference the new container image tag — no configuration, resource sizing, or scheduling changes are involved.

The two migration Jobs (Postgres via TypeORM and ClickHouse) follow the established pattern of creating new Job resources named after the incoming commit and deleting the old ones from the previous deploy. The new migration jobs will run against the databases before (or alongside) the rolling update of the application pods, so the new schema must be backward-compatible with the old code during the rollout window.

🔵 Info — The pulumi:providers:gcp warning about missing ADC credentials is cosmetic; it only affects GCP provider operations (none in this plan) and does not block the Kubernetes updates.
