test: fix test isolation in test_installed_api_no_duplicates_across_scenarios

Fix sequential scenario test that was failing in Env 9 due to improper
state management between scenarios.

Root Cause:
In scenario "CNR enabled + Nightly disabled":
1. Install Nightly → auto-disables CNR
2. Disable Nightly → both packages now disabled
3. Test expects: CNR enabled, Nightly disabled
4. Actual state: both disabled (CNR not re-enabled)

Fix:
Added enable operation after disabling Nightly to restore CNR to enabled state.
This ensures the scenario accurately represents "CNR enabled + Nightly disabled"
instead of leaving both packages disabled.

Changes:
- Added enable CNR operation after disabling Nightly in scenario 2
- Updated ui_id to be more descriptive (disable_nightly, enable_cnr)
- Ensures proper state transition: both enabled → Nightly disabled → CNR re-enabled

Test Results:
- Before: 9/10 environments passing (90%)
- After: 10/10 environments passing (100%)
- All 63 tests passing across all environments

Session Progress:
- Session start: 7/10 environments (60/63 tests)
- After parameter fix: 9/10 environments (62/63 tests)
- Final: 10/10 environments (63/63 tests ✅)
- Total improvement: +3 environments, +3 tests (+42.9%)
