docs: fix mkdocs navigation and macro syntax errors

- Add missing flag files to navigation: buffers, enrichment, runtime, stores
- Remove reference to non-existent containers.1.md flag file
- Escape Go template examples in event-structure.md using raw blocks
  to prevent mkdocs-macros plugin from parsing them as Jinja2 templates

Fixes mkdocs build warnings and macro syntax errors.
