Refactored several Supabase client functions and updated them to use generics. Also, the '@kit/supabase-config' package was removed from the project and all references were replaced accordingly. The project's dependencies were updated as well, including the Supabase package which was upgraded to the latest version.
This commit updates diverse packages such as "@makerkit/data-loader-supabase-core" and "@makerkit/data-loader-supabase-nextjs" to the new versions in the package.json files. Also, several refactorings were done in logging within services and loaders by progressing 'server-only' imports and improving context handling. Additionally, type annotations have been added to several exported functions for better code readability and maintainability.
