fifa17 store: make reward packs (SBC/draft/season/...) openable

SBC completion and the other Core reward services grant packs with symbolic
definition_ids ("silver_pack", "gold_pack", ...). The FIFA 17 pack system keys
entirely on numeric catalogue ids, and entitlement_pack_ids / handle_pack_open
resolved definition_ids with definition_id.parse::<u64>(), so every symbolic
reward pack was silently dropped from the openable My Packs list. The unopened
count (recoveredPacks, = entitlement count) still counted them, so the client
showed "you have N packs" but had no tile to open -> "no pack available".

Fix (adapter-layer, Core stays game-neutral): add owned-only reward pack
catalogue entries 71-75 (bronze/silver/gold/rare_gold/icon) and a resolver
owned_pack_id_for_definition() that maps both numeric owned ids and the symbolic
reward names to their numeric owned-only pack. entitlement_pack_ids and the
pack-open entitlement selection now use it, so reward packs render as openable
My Packs tiles and redeem their entitlement for free (consume-once, no debit).

Server-verified on staging: 3 Core reward entitlements now render 3 openable
mypacks tiles matching recoveredPacks=3. Tests: adapter resolver + rendering,
host symbolic-reward open flow; full adapter + host suites green.
