refactor: ♻️ clean up gallery code

- cast images collection to array for clarity in galleryObserver
- shorten debounce function
- do not destructure track object for isAtEnd (no space savings or readability improvements)
- remove unused argument in updateActiveStates
- call functions directly during page initialization
