feat(api): Enhance session events API with pagination, sorting, and filtering

- Added support for pagination (page and limit) in the session events endpoint.
- Implemented sorting functionality based on specified columns and directions.
- Introduced free-text search capability for session events.
- Updated SQL queries to retrieve all events and added a new SQL constant for events.
- Refactored GraphQL types and helpers to support new plugin and event queries.
- Created new GraphQL resolvers for plugins and events with pagination and filtering.
- Added comprehensive tests for new GraphQL endpoints and session events functionality.
