Rename coop to blog throughout codebase

- coop_url() → blog_url(), AUTH_APP default → "blog"
- Session cookie: coop_session → blog_session
- Config keys: coop_root/coop_title → market_root/market_title
- All Jinja templates: coop_url → blog_url, coop_title → market_title
- Template blocks: coop-child-header → blog-child-header
