fix(cli): stop treating subcommand -v as version flag (#1082)

## Summary

Fix `_is_help_or_version_command` so subcommand `-v` (the CSV output
alias on commands like `quota`) no longer skips authentication.
Top-level `kaggle -v` / `kaggle --version` still skip auth as before.

The duration parsing crash from #1064 is handled separately in
Kaggle/kaggle-sdk-python#58 (needs kapigen sync and a new kagglesdk
release).

## Root cause

`authenticate()` runs before argparse and joins `sys.argv[1:]` into a
string. `"quota -v".endswith("-v")` matched the global version check
even though `-v` here is the CSV flag, causing unauthenticated API calls
and 401s.

## Tests

Added `tests/unit/test_help_version_auth.py` covering top-level
version/help, subcommand CSV `-v`, and subcommand help.

## Test plan

- [x] `pytest tests/unit/test_help_version_auth.py`
- [ ] Maintainer: please run `/gcbrun` for Cloud Build (fork PR)
