fix: resolve 6 QA bugs in frontend admin panel (RCA-19)

Bug 1: Dashboard child route path "" → "dashboard" + redirect from /
Bug 2: Test localStorage key "admin_token" → "cb_admin_token"
Bug 3: Router setup check data.isSetUp → data.initialised
Bug 4: Setup wizard button text to match test selectors
Bug 5: loginViaAPI helper sets localStorage directly instead of hitting relay
Bug 6: Login button disabled when fields are empty
