Connected suite catches up with #102 and #103; the lending back-key case; the loopback stop test

[GonzRon]

Found by the 1.8.0 pre-cut connected gate (R2 on emulator-5554): the complete suite ran 430 tests in 78 classes with zero skips and 15 failures. None was the app misbehaving; the suite had not been run since #102 and #103 merged (CI runs no connected test).

• Dates (6 cases) — AssetModelDeviceProofTest, JournalDeviceProofTest ×2, ChangeConditionSheetTest, ServiceCaseScreensTest, AssetEditorSeasonAndHealthTest: since [1.8.0][LOCALIZATION] Android localization foundation and language packs #102 date fields draw the language's own order; the tests now take the expected text from the screen's own helpers (dateFieldText, monthDayFieldText); stored values stay ISO.
• GroupScreensTest (5 cases): since [1.7.1][UI/UX] Maintenance tab and Settings cleanup; move Reminder health to Utilities #103 the groups sit behind the Maintenance tab's "Maintenance groups" row; the test goes tab → row → list.
• ReminderHealthScreenTest (3 cases): waited for "Utilities" where the Settings heading is drawn in capitals; now waits for the resource, uppercased.
• LendingSectionDeviceTest.theBackKeyOnTheRationaleIsNotNow: not slowness — the soft keyboard came back over the rationale dialog and took the Back key; the test closes the keyboard after typing the date and sends Back to the dialog window. 3 of 3 runs, 2.5–3.0 s each.
• LoopbackApiServerTest.stopRefusesFurtherConnections (JVM; flaked once on CI): end of stream on the closed port is not an answer; any byte read still fails.

Eight classes re-run on the emulator, all green, zero skips. No main-source change.

Note for later (not in this PR): if the keyboard is up when "Save loan" raises the rationale, a person's first Back closes the keyboard and only the second counts as "Not now".
