Regression from the #832 server-side launch gate (Beckid). On a PIN-required,
unverified session the gate 401'd /api/setup/status — which the frontend checks
BEFORE the PIN screen. The 401 left setup_complete undefined, so `!undefined`
relaunched the full setup wizard on every visit (cancel → PIN screen worked,
which was the tell).
Two-layer fix:
- Allowlist /api/setup/status in the launch gate (it's a harmless boolean, no
secrets) so the frontend gets the real answer even while locked.
- Make the frontend fail-safe: only launch the wizard on a definitive
setup_complete === false from an OK response — never on a 401/locked/ambiguous
one.
Test: locked session still 401s data endpoints but /api/setup/status returns
{setup_complete:true}; added a gate-allowlist assertion. 21 gate tests pass.
