Fix COURSE_DATA_DIR default to ~/AutoNote (matching Electron app)

Root cause: Python scripts defaulted COURSE_DATA_DIR to DATA_DIR
(~/.auto_note) when OUTPUT_DIR was empty, but the Electron app's
getOutputDir() defaults to ~/AutoNote. Course data (captions,
materials, alignment) lives under ~/AutoNote, so Python saved the
mapping to ~/.auto_note where the JS scan couldn't find it.

Fix: all Python scripts (semantic_alignment, note_generation,
frame_extractor) now default COURSE_DATA_DIR to ~/AutoNote when
OUTPUT_DIR is not set — matching the Electron app's behavior.

JS align:scan also updated to check OUTPUT_DIR first, DATA_DIR
as fallback.

Verified end-to-end: Python saves mapping to ~/AutoNote/88787/,
JS align:scan finds it there.
