 * Point Progression Tests
 * Phase 4.6: Test point progression data formatting
 *
 * Note: These are unit tests that test the data formatting logic.
 * Integration tests with actual database are in the e2e test suite.
 * The getSeasonPointProgression function queries the database directly,
 * so we're documenting its expected behavior here.
