feat: add federation processed activities table and update dependencies

- Created a new SQL migration to add the `federation_processed_activities` table with an index on `processed_at`.
- Updated dependencies in `Cargo.toml` files across `bootstrap` and `worker` crates, including version updates for `k-ap`.
- Enhanced the event publishing mechanism in the `factory.rs` file to include a new `KapPublisher` for handling federation events.
- Refactored the `build` function in `factory.rs` to accommodate the new event publisher and improve ActivityPub service initialization.
- Modified the worker's main loop to handle new federation event types and improved error handling for event processing.
