📄 Description

Problem

The application fails to start on Python 3.13 due to a matplotlib import error when importing fastf1.plotting at module level.

Solution

Made fastf1.plotting import lazy (only when needed)
Added fallback color scheme when plotting module cannot be imported
Application now works even if matplotlib has compatibility issues

Changes

Removed top-level import fastf1.plotting
Wrapped import in try/except with fallback in get_driver_colors()
Added team-based color mapping as fallback

Testing

Tested on Python 3.13 where original code failed. Application now starts successfully.
