Add error handling, enhance syncing, and refactor deletion logic

- Introduce new error messages for syncing and book deletion in `en.json`.
- Update `DeleteBook` to support local-only deletion and synced book management.
- Refine offline/online behavior with `deleteLocalToo` checkbox and update related state handling.
- Extend repository and IPC methods to handle optional IDs for updates.
- Add `SyncQueueContext` for queueing offline changes and improving synchronization workflows.
- Enhance refined text generation logic in `DraftCompanion` and `GhostWriter` components.
- Replace PUT with PATCH for world updates to align with API expectations.
- Streamline `AlertBox` by integrating dynamic translation keys for deletion prompts.
