Backend:
- Auth controller sets httpOnly secure cookies (access_token, refresh_token, goodgo_authenticated) on login/register/refresh
- JWT strategy reads token from cookie first, falls back to Authorization header
- Added POST /auth/logout to clear auth cookies
- Added POST /auth/exchange-token for OAuth callback token-to-cookie exchange
- Refresh endpoint reads refresh_token from cookie (body fallback for backwards compat)
- CSRF middleware excludes auth endpoints (login, register, refresh, exchange-token, logout)
Frontend:
- Removed all localStorage token storage (goodgo_tokens key)
- Removed authGet/authPost/authPatch helpers from api-client (tokens sent via cookies)
- All API calls use credentials:'include' for cookie-based auth
- Updated auth-store: no more token state, uses isAuthenticated flag from cookie
- Updated admin-api, listings-api to remove explicit token parameters
- Updated all pages (admin dashboard, users, KYC, moderation, listings) to remove token passing
- OAuth callbacks use exchange-token endpoint to convert URL tokens to cookies
- Auth provider simplified (no client-side cookie management needed)
Security improvements:
- JWT no longer accessible via JavaScript (XSS-safe)
- Refresh token scoped to /auth path only
- Server-side goodgo_authenticated cookie with SameSite=Lax
- Access token cookie with SameSite=Strict
