Fix dashboard auth JSON handling
Some checks failed
deploy / deploy (push) Failing after 35s
Details

Browse source 
Proof: npm test (212/212) and npm run operator-dashboard:build cover non-JSON auth failures and rebuilt the dashboard bundle.

Assumptions: browser auth failures may return plain text before a session cookie is established; API callers should receive JSON errors.

Still fake: dashboard quote outcomes still depend on inventory-delta attribution instead of venue-native terminal fill events.
