[Feature] Add Route Editing and Saving Functionality in Routing Module

[daohu527]

Description

Currently, the routing interface only supports basic point selection on the map. We need a more flexible way to create, edit, and persist custom routes based on point cloud maps or HD maps.

Current Limitation

• Users can only select discrete points on the map.
• Lack of path smoothing and manual adjustment capabilities.

Proposed Features

1. Curve Generation: Automatically generate a smooth curve/path when two points are selected on the map.
2. Path Editing: Support interactive editing of the generated curves (e.g., dragging waypoints or adjusting curvature).
3. Route Persistence: Ability to save the edited route so the vehicle can follow the predefined path in subsequent sessions.

Workflow

• Load the Point Cloud/HD Map.
• Interactively plot and refine the route on the UI.
• Save and execute the planned trajectory.
