Refactor event payload handling across adapters

- Introduced `event-payload` crate to centralize event payload definitions.
- Updated NATS and PostgreSQL adapters to use the new `EventPayload` type.
- Removed redundant event payload definitions and conversion implementations from NATS and PostgreSQL adapters.
- Simplified SQLite event queue to utilize the new `EventPayload`.
- Refactored wiring functions for PostgreSQL and SQLite to improve database connection handling and migration.
- Cleaned up presentation and worker crates by removing unused event publisher dependencies and related wiring functions.
