feat(api): define core api and applcition specific code

* Refactor Waku message handling to use OutboundPacket

- Updated the `UserAction` enum to replace `SendToWaku` with `Outbound`, streamlining message processing.
- Refactored `WakuNode` and related components to utilize the new `OutboundPacket` struct for sending messages.
- Enhanced error handling and message conversion logic to improve clarity and maintainability.
- Updated tests to reflect changes in message handling and ensure compatibility with the new structure.

* Refactor message handling to utilize InboundPacket and DeliveryService

- Replaced `WakuMessage` with `InboundPacket` across various modules to streamline message processing.
- Updated `Gateway` and `User` structs to send and receive messages using the new `DeliveryService`.
- Refactored topic filtering logic to accommodate the new message structure, enhancing clarity and maintainability.
- Removed deprecated `net.rs` and `waku_actor.rs` files, consolidating message handling into the `transport` module.
- Enhanced error handling and logging for improved traceability during message processing.
- Updated tests to reflect changes in message handling and ensure compatibility with the new structure.

* Enhance Gateway and CoreCtx to support generic DeliveryService

* Remove unused dependency `async-trait` from `Cargo.lock` to streamline project dependencies.

* fix lint error

* fully moved to hashgraph-consensus library

* Define identity and openmls api

* Present de-mls api

* Refactor group management logic and voting

* Enhance consensus handling and UI integration

- Introduced new epoch history management in the `User` and `Gateway` structs to track past batches of approved proposals.
- Updated the `push_consensus_state` function to push epoch history and approved queue events to the UI.
- Refactored the `GroupHandle` and `CurrentEpochProposals` to support epoch history, ensuring that approved proposals are archived after processing.
- Enhanced the desktop UI to display epoch history and improve user experience during group management and voting processes.

* Implement group state management and UI updates

- Added a new `group_state` field to the `ConsensusState` struct to track the current state of the group.
- Enhanced the UI to display group state changes, including new styles for warning and muted states.
- Introduced event handling for group state changes in the `GatewayEventHandler`, allowing the UI to react to state updates.
- Updated the `User` struct to handle state transitions, including entering and leaving groups, with appropriate notifications to the UI.
- Refactored group management logic to support the new state handling, ensuring a seamless user experience during group operations.

* Refactor group management and enhance state handling

- Removed the `GroupRegistry` struct to simplify group management logic.
- Updated the `Gateway` and `User` structs to eliminate references to the removed `GroupRegistry`.
- Introduced a new `GroupConfig` struct to manage group-specific configurations, including epoch duration.
- Enhanced the `GroupStateMachine` to support custom configurations and added commit timeout handling.
- Updated the `create_group` and `create_group_with_config` methods to utilize the new configuration system.
- Improved documentation across modules to clarify usage and functionality of the new structures and methods.
