chore: remove manager-era NBA test files and one-off debug scripts

The four test_nba_*.py files imported nba_managers, leaderboard_manager
and odds_manager — top-level modules deleted when sports displays became
plugins — inside try/except blocks that swallowed the ImportError, so
they passed while exercising nothing. test_nba_data_structure.py and
debug_nba_api.py (a diagnostic script living in test/) made live ESPN
API calls rather than testing repo code. None were enrolled in CI.

scripts/debug/direct_fix_imports.py and check_imports.py were one-shot
artifacts that edited/inspected a hardcoded ~/LEDMatrix/web_interface/
app.py to fix an import problem solved long ago; nothing references
them.
