fix: skip lofn for My Feed time-ordered feed

[pnvasanth]

Summary

• When "My Feed" is ordered by date, use FeedPreferencesConfigGenerator with CustomFeedNaV1 config instead of FeedLofnConfigGenerator
• Skips lofn roundtrip entirely — uses chronological retriever, no reranking, engagement filter disabled
• All user preferences/filters (blocked tags, sources, words, followed sources/users, post types, content curation) still applied

Test plan

• Updated existing integration test to verify no lofn mock needed and correct config (custom_feed_na_v1, order_by: date, disable_engagement_filter: true)
• Added unit test for versionToTimeFeedGenerator verifying chronological config properties
• All existing feed tests pass
• Lint passes

🍹 The Update (preview) for dailydotdev/api/prod (at 4dd4bdb) was successful.

✨ Neo Explanation

This is a standard application deployment rolling out a new version across all API services, workers, and scheduled jobs, with accompanying database and ClickHouse migrations for the new release.

Root Cause Analysis

A new version of the API application has been built and is being deployed. Every Kubernetes resource is being updated to point to the new container image for the new application version.

Dependency Chain

The new application version triggers updates across the entire fleet of workloads that run this image:

• 7 Deployments (API, background workers, WebSocket server, private, Temporal, personalized digest, worker jobs) will perform rolling updates to the new image, replacing pods gradually with zero downtime.
• 34 CronJobs will have their job templates updated so that the next scheduled execution uses the new image.
• 2 one-time migration Jobs (Postgres DB migration and ClickHouse migration) from the previous deployment are deleted, and 2 new equivalents are created for the new version — these run the database schema migrations required for the new release.

Risk Analysis

No risky changes detected. All deployments are rolling updates with no stateful resource replacements or deletions. The migration jobs are ephemeral by design — old jobs from the previous version are cleaned up and new ones are created. There is no data loss risk.
