Remove plaintext password leak from admin auth log

[Copilot]

The admin authorize callback was logging the full credentials object on successful login, exposing plaintext passwords in server logs.

Changes

• app/api/auth/[...nextauth]/route.ts — Removed console.log("LOGIN ATTEMPT:", credentials) from the admin credentials authorize callback.

// Before
if (!ok) return null;
console.log("LOGIN ATTEMPT:", credentials); // ← leaked plaintext password

return { id: admin.id, email: admin.email, ... };

// After
if (!ok) return null;

return { id: admin.id, email: admin.email, ... };
