Consolidate CLI tools and fix git aliases

- Consolidated 25+ common CLI tools into modules/common/base.nix
- Added modern rust-based tools (eza, bat, ripgrep, etc.) system-wide
- Removed duplicated packages from user and machine configs
- Added consistent shell aliases for modern CLI tools
- Fixed gpa alias to properly push to all remotes
- Removed duplicate git-push-all alias from geir.nix
- Added comprehensive documentation in CLI_TOOLS_CONSOLIDATION.md

Benefits:
- Single source of truth for common CLI tools
- Reduced duplication across 7+ configuration files
- Improved git workflow with flexible multi-remote pushing
- Better maintainability and consistency
