refactor: consolidate 3 DOMContentLoaded listeners into single init block

- Extract initTabState, initTabWheelScroll, initVisibilityPolling,
  initChatImagePreview, initModalAccessibility as named functions
- Move polling interval vars to outer scope for accessibility
- Single DOMContentLoaded calls all init functions in logical order
- Replace scattered listeners with comment markers at original locations
