Pull Request Overview

This PR adds automated onroad UI screenshot generation by feeding the UI with real route data and VisionIPC frames, and introduces cases for onroad alerts and states.

• Initialize VisionIPC and publish migrated log events to drive the UI for onroad screenshots
• Add helpers for onroad alert scenarios (small/mid/full, disengaged, override, wide, sidebar, driver cam)
• Cache and reuse a set of camera frames for faster test execution

The cache filename is not specific to the route/segment; running tests with different routes or segments risks stale or mismatched frames. Include route name and segment (and optionally camera profile) in the cache key, e.g., DEFAULT_CACHE_DIR/test_ui_frames_{route.fullname}_{segnum}.npz.

Suggested change

	frames_cache = f"{DEFAULT_CACHE_DIR}/test_ui_frames"
	# Make cache filename specific to route and segment
	safe_route_name = route.fullname.replace("/", "_")
	frames_cache = f"{DEFAULT_CACHE_DIR}/test_ui_frames_{safe_route_name}_{segnum}.pkl"
