fix: resolve daily personalise state via snotra user API

[capJavert]

Problem

FeedDailyConfigGenerator resolves the user's personalise state to pick between daily_v1 (personalised) and daily_cs_v1 (cold start). It was constructed with the shared snotraClient, which points at SNOTRA_ORIGIN (the snotra memory API). That origin serves /api/v1/memstore/shortprofile but not /api/v1/user/profile, so every getUserProfile call fails with a 404.

Because resolvePersonaliseState swallows the error and returns undefined, the generator always falls back to the personalised config:

• daily_cs_v1 is never selected in production (zero requests in fss_events over the last 20 days).
• Cold-start users (no sauron embeddings yet) get an empty daily feed from daily_v1 — observed via the failed to resolve snotra personalise state for daily feed error logged on every dailyHeadlines request, and a chunk of daily-posts responses returning 0 posts for recently onboarded users.

Fix

Add snotraUserApiClient pointing at SNOTRA_USER_API_ORIGIN (the same origin the personalized digest flow already uses for getUserProfile) and wire it into dailyFeedConfigGenerator. Existing snotraClient consumers (getProfile / memstore endpoints) are untouched.

Verified daily_cs_v1 itself returns posts when exercised directly against the feed service with production-shaped payloads, so fixing state resolution is enough to restore the cold-start path.

Tests

Updated the getUserProfile spies in __tests__/feeds.ts to target the new client.
