[TOL-2311] Add --force to logout paths in case revoke on server fails

[omc-tollbit]

What does this PR do

• tollbit auth logout now fails closed when it can't revoke the refresh token server-side, instead of leaving credentials on disk with a confusing error.

  • Default: if revocation can't reach the server, local credentials are kept and the command exits non-zero with a clear message ("you're still logged in, retry when online").
  • --force: clears local credentials even when revocation fails, with a warning — the token is revoked at your next login or expires within 30 days.

• Both logout and logout --all share the behavior (via ClearAuthTokens). auth set is unchanged.
