teknium1 e63da95318 fix(cli): auth.json-only login with a benched credential is explained, not sent to the wizard
Two gaps from review of #113720's fix:

1. A profile logged in via auth.json (active_provider: nous) with no
   model.provider in config.yaml resolves as "auto". The ladder's OAuth rung
   swallowed the AuthError for "auto" and fell through to the keyless OpenRouter
   fallback, so the startup probe returned (False, None) and the first-run
   wizard ran anyway. The ladder now catches the AuthError in _ladder_rungs,
   still falls through for "auto", but stamps the swallowed error on a keyless
   fallback as `auth_error`; _probe_runtime_credentials returns it so the notice
   names the real failure.

2. The gate itself lived only in cli.py::_tui_print_startup and was untested at
   the seam (reverting cli.py left the suite green). It is now one mixin method,
   _maybe_offer_first_run_setup (tty check → probe → explain → offer), called
   from _tui_print_startup, and both tests drive that method with stdin.isatty
   patched True and _offer_first_run_setup asserting it is not called.

Tests: the benched-credential test now covers the gate and the cooldown headline
wording; the blank-install control is folded into the new auth.json-only test.
