* fix(#478): rework default login to use unified ConnectionProfile model - AuthManager: drop legacy auth_token path; getToken/setToken now delegate to the selected profile (profile token only, no global fallback) - setHost/setPort always write the selected profile (no top-level host/port branch) - Add DEFAULT_PROFILE_ID + ensureDefaultProfile()/ensureDefaultSelected() so the selected profile is never null; ensureDefaultSelected() only falls back when nothing is selected (never clobbers an existing choice); ensureDefaultProfile() only injects a Default profile on fresh install, never into an existing list - One-time migration folds legacy standalone auth_token into the Default profile, batched into a single SharedPreferences transaction (guarded by legacy_default_migrated) - ConnectViewModel.connect() persists via setToken/setHost/setPort (delegate to the selected profile) — keeps the existing persistence contract - Connect/Settings: remove the '(none)'/standalone profile option; deleteProfile falls back to Default profile instead of null selection - Update AuthManagerTest/ConnectViewModelTest to the unified model; fix test stub ordering + migration re-init; remove dead connect_profile_none / settings_profile_none strings Closes #478 * fix: stub AuthManager.ensureDefaultSelected() in E2eIntegrationTest The #478 ConnectViewModel.connect() success branch now calls AuthManager.ensureDefaultSelected() on the non-saveProfile path. E2eIntegrationTest.setUp() mocks AuthManager as a non-relaxed mockkObject but never stubs that method, so the unstubbed call throws MockKException inside viewModelScope.launch, leaving connectionSuccess unset and failing 3 tests: - testFullUserSessionFlow - testConnectViewModel_onPairingString_base64Format - testConnectViewModel_onPairingString_urlFormat Add the missing stub. Verified locally: full suite 322/322 passing. --------- Co-authored-by: ronia <ronia@m57>
