Fix scheduled publishing date issue and deploy working blog v1.1.1

- Root cause: publishDate was set for future dates (Aug 28/29) when current time is Aug 27
- Fixed by updating publishDate to Aug 27 09:00 UTC (in the past)
- Scheduled post now appears correctly on blog homepage and RSS feed
- Blog v1.1.1 successfully deployed with working scheduled publishing

Issue resolved:

✅ Post included in RSS feed with full content
✅ Direct post URL accessible: /posts/2025-08-29-on-prem-gpus
