docs(fifa17): record empty My Packs client contract

Full investigation record for bug 6c: baseline + Experiments A/B/C', Candidate F (contradicted), the explicit active-placeholder selection test, the minidump-confirmed CardsDLL crash, and the P2 decision. Marks ROOT CAUSE ESTABLISHED and documents the known UX limitations and the client-side follow-up. Files: docs/evidence/STORE_TILE_6C.md, docs/evidence/FIFA17_EMPTY_MYPACKS_CLIENT_CONTRACT.md, the four genuine /store/purchasegroup captures (baseline, mypacks70, empty_no_sentinel, active_placeholder), and docs/plans/FIFA17_EMPTY_MYPACKS_CLIENT_FIX.md (client-side design/research).
