FN-6319: quarantine flaky engine tests

Browse Source 
Quarantine unrelated engine test flakes so the gate avoids known unstable fixtures.

- Add the soft-delete blocker residue reliability test to the quarantine ledger and reliability interaction exclusions.
- Add the bubblewrap sandbox backend test to the quarantine ledger and engine-core exclusions.
