fix: re-init scroll animations after data loads from DB

- initScrollAnimations ran only on firstRender when data wasn't loaded yet
- Items with fade-in-up class stayed invisible (opacity:0) after data render
- Now tracks _dataLoaded/_animationsInitialized flags to re-init JS after data loads
- Also fixes stat counter animations not running (stats were empty on firstRender)
