refactor: Migrate Node dropdown menu to Compose

[jamesarich]

Migrated the Nodes dropdown menu to Compose, replacing the old XML-based UI. This change improves the maintainability and flexibility of the UI, allowing for more dynamic and interactive elements. It also simplifies the codebase by reducing the need for separate XML menu.

The refactoring includes:

• Removed XML menu and related code.
• Created composable functions for NodeMenu and MenuItemAction.
• Updated SimpleAlertDialog to support confirmation action.
• Updated NodeItem to use the new NodeMenu and MenuItemAction.
• Updated UsersFragment to handle NodeMenu actions and navigation.

Thanks for the review, was noticing that the dropdown wasn't anchored to the chip and went on a refactoring spree 😅 . I'll get it cleaned up.

As per discord discussion:

using "isConnected = model.isConnected()" wont trigger recompositions when connection state changes it needs to collect the state directly or in the nodesUiState
