feat(controllers): optimize caching and view data passing

- Refactored the ChampionController, ChampionSkinController, HomeController, SaleController, SummonerEmoteController, and SummonerIconController to use arrow functions for cache callbacks.
- Updated the view data passing in the ChampionController, ChampionSkinController, HomeController, PostsController, SaleController, SummonerEmoteController, and SummonerIconController to use associative arrays instead of compact().
- Removed unused imports from web.php.
