Extract common helper functions from test-phase1.sh, test-phase2.sh,
and test-phase3.sh into a shared library (alarm-test-lib.sh) to reduce
code duplication and improve maintainability.
Changes:
- Create alarm-test-lib.sh with shared configuration, UI helpers, ADB
helpers, log parsing, and test selection logic
- Refactor all three phase test scripts to source the shared library
- Remove ~200 lines of duplicated code across the three scripts
- Preserve all existing behavior, CLI arguments, and test semantics
- Maintain Phase 1 compatibility (print_* functions, VERIFY_FIRE flag)
- Update all adb references to use $ADB_BIN variable
- Standardize alarm counting to use shared count_alarms() function
Benefits:
- Single source of truth for shared helpers
- Easier maintenance (fix once, benefits all scripts)
- Consistent behavior across all test phases
- No functional changes to test execution or results
