[SDK-115] Harden BCIT tests against Ubuntu+KVM launcher ANRs

CI run on PR #1064 surfaced four failures that all share the same root
cause: the Pixel Launcher ANRs on Ubuntu+KVM during heavy parallel work
and steals focus from the activity-under-test, so findObject().exists()
returns false even though the view is in the tree (logcat shows
`current package: android` instead of `com.iterable.integration.tests`).

Three fixes:

1. BaseIntegrationTest.setUp now pressBack/pressHome to dismiss any
   lingering system dialog before the test runs. Universal CI-emulator
   hardening; benefits every test class that extends BaseIntegrationTest.
2. EmbeddedMessageIntegrationTest + DeepLinkIntegrationTest now use
   findObject().waitForExists(5000) instead of bare .exists().
   ActivityScenario reports RESUMED before the view tree is fully
   rendered; waitForExists handles the race. Same pattern as
   PushNotificationIntegrationTest already uses.
3. activity_main.xml is now wrapped in a ScrollView so the Test Scenario
   buttons stay reachable even when the override card grows.

Local verification: `Tests 7/7 completed. (0 skipped) (0 failed)` for
the full non-push suite with `ci=true`.
