chore(nix): cleanup flake.lock by removing unused inputs

- Removed unused inputs such as `flake-compat_2`, `flake-utils-plus_2`, and `nixpkgs_5` from `flake.lock`.
- Simplified configuration by consolidating redundant inputs and updating references.
- Aligns with best practices for maintaining a clean and efficient flake configuration.
