fix: send canonical history summaries to bragi

[idoshamun]

What changed

• Populate canonical history summaries from the backing post before sending current highlights to Bragi.
• For canonical rows stored on public share fallbacks, use the underlying shared post summary.
• Add regression coverage for canonical history stored on a fallback share over an unknown-source post.

Why

Bragi's second-pass dedup can compare candidate summaries against current highlight summaries, but canonical history rows backed by share fallbacks were reaching Bragi without the underlying post summary. This made semantic duplicate detection weaker for cases like repeated coverage of the same model launch.

Validation

• NODE_ENV=test npx jest __tests__/cron/channelHighlights.ts --testEnvironment=node --runInBand

🍹 The Update (preview) for dailydotdev/api/prod (at d7df739) was successful.

✨ Neo Explanation

Routine deployment updating all workloads to a new image tag; the functional change improves summary fallback logic for canonical share highlights in the channel highlights cron. ✅ Low Risk

This is a routine code deployment rolling out commit 9aab023d (replacing e4b35954) across all deployments and cron jobs. The code change fixes channel highlight summary resolution for canonical share posts — when a highlighted post is a share of an article from an unknown/external source, the cron now correctly falls back to the underlying article's summary rather than returning null.

The migration jobs (both DB and Clickhouse) are being cycled to the new image hash as expected for this deploy pattern.
