feat(blog): add scripts for date fixes, categories, and governance banners

Three scripts to support blog system improvements:

1. fix-blog-dates.js
   - Fixes empty {} published_at values in database
   - Sets proper ISODate values for 3 blogs
   - Also updates moderation.approved_at for consistency

2. add-blog-categories.js
   - Adds category field to all blog posts
   - Maps content to standardized categories (Framework Updates,
     Implementation, Case Studies)
   - Enables category filtering functionality

3. add-vetting-notice-to-architectural-boundaries.js
   - Adds comprehensive human vetting notice
   - Documents AI-curated content review process
   - Shows governance working end-to-end with inst_017 compliance

Applied to both tractatus_dev and tractatus_prod databases.
