Wire IBattlePassService.GetLevelCurveAsync into LoadController so /load/index
emits the 100-entry battle_pass_level_info dict when levels are seeded.
Also adds BattlePassRepository.ResetLevelCurveCache() to bust the process-level
static cache in tests that seed levels after earlier HTTP calls have primed it
with an empty list, and updates SVSimTestFactory.SeedGlobalsAsync + the stale
Index_surfaces_seeded_globals_after_bootstrap assertion accordingly.
