This commit introduces a new `Modifier.onRightClick` extension to improve desktop usability by mapping secondary mouse clicks to existing long-click actions. It also removes the legacy desktop `MenuBar` implementation in favor of this more consistent cross-platform UX approach.
Specific changes include:
- **Core UI**: Added `Modifier.onRightClick` in `ModifierExtensions.kt` using `PointerButton.Secondary` to detect right-clicks on desktop platforms.
- **Desktop**: Removed the `MenuBar` and associated keyboard shortcuts from the main entry point.
- **Messaging Feature**: Added right-click support to `MessageItem`, `Reaction`, and `ContactItem`.
- **Node Feature**:
- Added right-click support to `NodeItem`, `NodeDetailsSection`, `NodeDetailComponents`, and `InfoCard` to trigger copy actions or context menus.
- Updated `TracerouteLog`, `NeighborInfoLog`, and `NodeItem` to handle right-click events.
- **Connections Feature**: Updated `DeviceListItem` to support right-click for deletion/context actions.
- **Documentation**: Updated `roadmap.md` to reflect the completion of right-click UX integration.
