Fix align:scan path resolution — check DATA_DIR first, not OutputDir

Root cause: align:scan looked for course data under getOutputDir()
(~/AutoNote by default) but Python saves under DATA_DIR (~/.auto_note).
On the user's machine ~/AutoNote/COURSE_ID may exist (from previous
pipeline runs) so the fallback never triggered, and the mapping file
was never found.

Fix: scan all candidate locations (DATA_DIR first, then OutputDir)
and pick whichever has the captions/ directory. This matches Python's
COURSE_DATA_DIR resolution logic.
