Fix events CRUD for standalone events and add events to admin menu

- event_params now permits title, description, is_primary
- event_information helper lists all node.events, not just the first
- Occurrence.generate handles nil node (standalone events)
- Page.aggregate order_by title uses correlated subquery to avoid
  GROUP BY conflict with tag-filter path; order_direction whitelisted
  to ASC/DESC to prevent SQL injection
- Events link added to admin menu bar
- events/index shows title, is_primary; drops latitude/longitude columns
