This change addresses a security vulnerability where the `USER` environment variable was used to determine the current user identity. This variable can be spoofed by an attacker, potentially leading to privilege escalation or unauthorized actions. We now use `nix::unistd::User::from_uid(Uid::current())` to securely determine the current user based on the effective user ID. This ensures that the application operates on the correct user account. The `nix` dependency was added to `Cargo.toml` to support this functionality. The logic in `src/app/mod.rs` was updated in two places: 1. Initializing `selected_user`. 2. Fallback logic when `AccountsService` returns no users. Verification: - `cargo check` passes. - `cargo test` passes. - Dependencies installed: `libxkbcommon-dev`, `libdbus-1-dev`, `libglib2.0-dev`, `libwayland-dev`.
