Test infra: shared accessibility IDs + PageObjects + AAA_SeedTests

Ports iOS HoneyDueUITests AccessibilityIdentifiers + PageObjects pattern
to Android Compose UI Test. Kotlin AccessibilityIds object mirrors Swift
verbatim so scripts/verify_test_tag_parity.sh can gate on divergence.

AAA_SeedTests bracketed first alphanumerically; SuiteZZ cleanup to follow.
