Bumps k-ap to 0.3.1 which adds bio, banner_url, followers_url,
following_url, and also_known_as to RemoteActor. These are populated
from fetched actor JSON at follow/ingest time so followers and following
listings no longer return null profile fields.
Adds migration 015 for the new remote_actors columns, updates all JOIN
queries in postgres-federation to select and return the new fields, and
maps them through k_ap_actor_to_domain.
Also fixes clippy: remove empty line after doc comment in port.rs.
- 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.
