Bucket A: drop tests referencing archived artofwar-decoy-sacrifice

The pack was moved to scenarios/packs/_archive/ but tests still
referenced it as if active.

- Mark _archive/artofwar-decoy-sacrifice.yaml status: quarantine so
scenarios/loader.discover_packs() (and the Scenarios catalog in
app.py) skip it from the active set.
- tests/test_artofwar.py: drop the pack from the FAMILY parametrize
list and remove test_decoy_hard_loss_cap_allows_bait_not_army.
- tests/test_hard_tier.py: drop the pack from UPGRADED.

The sister art-of-war packs (artofwar-indirect-approach,
artofwar-lure-the-tiger, artofwar-sequenced-citadel) cover the
decoy/sacrifice idiom in the active catalog.
