Refactor and enhance event handling, database logic, and replaceable event processing

- **main.go**: Replace `ratel` storage backend with `database.New` for enhanced reliability and error handling.
- **database/query-events.go**: Rewrite event querying to handle replaceable and parameterized replaceable events; introduce deletion-based filtering, and improve sorting logic.
- **realy/addEvent.go**: Remove unnecessary logging for ephemeral events to optimize processing.
- **database/query-events_test.go**: Add comprehensive tests for replaceable events, parameterized replaceable events, and deletion handling to validate new logic.
