fix: delegate analyze_scene_source to analyze_scene_source_with_hint

Remove duplicate implementation in analyze_scene_source() and replace
with simple delegation to analyze_scene_source_with_hint(source_dir, None).

This eliminates ~50 lines of duplicated logic that could drift apart
from the main implementation. Updated the test to verify the new
behavior where sources without scene-kind meta tag default to
ReportCollection instead of being rejected.
