feat: enhance documentation and server startup flow

- Add comprehensive API and CLI documentation for event receiver, asset/vulnerability diffing, settings management, and function evaluation
- Improve event receiver startup by separating StartEventReceiver() from StartListener() for better control over trigger registration timing
- Update README with new command examples for db list, func eval, and event-driven triggers
- Refactor PrintStartupInfo to display detailed trigger information with tree formatting and better visual hierarchy
- Change trigger registration logging from Info to Debug level to reduce noise
- Clarify --workspace flag documentation in run/scan commands
- Add Type field to EventReceiverTriggerInfo for better trigger visibility in API responses
