fix: support camelCase property names from Indiekit Eleventy preset

The Indiekit Eleventy preset uses camelcaseKeys to convert frontmatter
properties (e.g., bookmark-of → bookmarkOf), but templates expected
underscore-separated names (bookmark_of).

Changes:
- Support both camelCase and underscore property names in all templates
- Update collections to filter on both property name formats
- Include interaction URLs (bookmarks, likes, replies, reposts) in
  Bridgy syndication content for proper social media posting

Fixes bookmark URLs not appearing on posts or in syndicated content.
