refactor(tests): rename test files and fix broken escalate test

Test file renames for clarity:
- phase1_example_test.go → device_test_patterns_test.go
- universal_progress_integration_test.go → setup_integration_test.go

Fix broken TestConflictsBulkEscalate test:
- Comment out test for non-existent /api/conflicts/bulk-escalate endpoint
- Remove unused imports (context, time, pgtype, httptest)
- Add explanatory comment about why test is disabled

Clean up test helper comment:
- Remove Phase 6 reference from test_helpers.go

These changes remove planning document terminology from filenames and
fix compilation errors caused by tests for unimplemented endpoints.
