* fix(testing): add MockCacheManager.get_cached_data_with_strategy/save_cache
ledmatrix-leaderboard's data_fetcher.py calls these two real-CacheManager
methods (src/cache_manager.py:313,817), but MockCacheManager had neither --
update() always hit an AttributeError, caught by a broad except and logged,
so the harness rendered an empty-but-green leaderboard on every test run
without ever exercising real standings data.
Both mocks delegate to the existing get()/set() -- a mock doesn't need the
real strategy's per-data-type max_age/market-hours timing, plugins under
test just need the methods to exist and round-trip whatever was cached.
* fix(testing): clear get_cached_data_with_strategy_calls in MockCacheManager.reset()
reset() cleared get_calls/set_calls/delete_calls but not the newer
get_cached_data_with_strategy_calls tracker, so a reused mock (e.g. across
test cases sharing a fixture) retained stale strategy-call records after
reset().
