feat(cli): translate --help text to Spanish

- Replace all hardcoded argparse help strings with t() calls
- Help text now displays in Spanish when --language es is used
- Works because _pre_resolve_language() runs before argparse
- Description, all argument help, epilog examples remain English (code examples)
