docs(blog): correct promote status in the dead-analytics post

[TimeToBuildBob]

The published post says the live bundle is still the old one. Production promoted at 08:06Z on 2026-09-16 and the live bundle now carries the PostHog key.

Also avoids overclaiming: the only $lib=web events since are from a localhost preview, so instrumentation is proven present, not yet proven live by real traffic. Source corrected in ErikBjare/bob@c496ab7126.

This PR updates a blog post about a PostHog analytics outage to correct the status of the production deployment. It changes the text to state that the fix PR merged at 19:01 UTC, the live bundle remained old for the rest of that evening, and production promoted at 08:06 UTC the next morning, with the live bundle now carrying the key. It also adds a caveat that the only $lib=web events since are from a localhost preview, so instrumentation is proven present but not yet proven live by real traffic.

Safe to merge — no P0/P1 findings

Confidence 5/5

✅ No findings. The diff looks correct to me on this pass.
