feat: Refine Trip Visualization and Marker Appearance

[regeter]

This PR introduces several key improvements to the map visualization, focusing on providing a more consistent and visually intuitive experience for tracking vehicle trips.

Key Changes:

1. Consistent Polyline Coloring for Multi-Trip Vehicles:

   • What: Fixes a bug where a vehicle assigned to multiple trips (e.g., back-to-back trips) would generate a new polyline color. The vehicle's path now maintains a single, consistent color based on the first trip ID in its assignment.
   • Why: This was causing visual fragmentation and made it difficult to follow the vehicle's complete journey. The fix ensures a continuous and predictable visual representation.

2. Trip-Based Coloring for Markers:

   • What: Pickup and dropoff markers are no longer hardcoded with their own colors. They now inherit the color of the trip polyline they belong to. Also adding a black stroke outline for better distinction from the trip polyline that now has the same color.
   • Why: This creates a strong visual link between a trip's path and its start/end points, which is especially helpful when multiple trips are displayed on the map simultaneously.
