feat(messages): Implement reply functionality

This commit introduces the ability to reply to messages.

- **API & Data Layer:**
  - Replaced `replyTo` parameter with `forward` in `sendMessage` calls across the data, domain, and repository layers to support the new reply mechanism.

- **ViewModel:**
  - Added logic to handle the reply state, including storing the replied message's ID (`replyToCmId`).
  - When a message is sent, it now correctly constructs a `forward` JSON object if it is a reply.
  - The UI state (`MessagesHistoryScreenState`) is updated to show and hide the reply preview.
  - Added a `onReplyCloseClicked` handler to cancel a reply.
  - The ViewModel interface was removed, and the implementation class `MessagesHistoryViewModelImpl` is used directly.

- **UI (Compose):**
  - A new `ReplyContainer` is displayed above the message input bar when a reply is active.
  - The input bar's corner radius animates to integrate with the reply container.
  - Added a `FocusRequester` to automatically focus the input field when the reply action is selected.
  - Added spacing in the message list to prevent the reply preview from overlapping messages.
  - The message options dialog now passes the `messageId` and `cmId` when an option is picked.
