feat(fifa17): import consumable + staff content as first-class Core content

Close 20 of the 33-record content gap (17 consumables + 3 staff; 13 Legends are
unrecoverable from PC data). Verdict A (no Core change): consumables/staff become
ordinary Core CardDefinitions (neutral player fields + honest family/role names)
and owned instances via the SAME generic import path; a catalog kind lets the
adapter exclude them from the player-only /club projection.

- adapter fut::content_taxonomy: evidence-based cardsubtypeid->family/label
  (Ghidra-derived ranges) + staff role map; unknown subtype => defer, never fabricate.
- adapter catalog: Fifa17CardIdentity/RawCard gain optional kind+subtype
  (backward-compat: legacy catalogs load as player); kind_of/subtype_of lookups.
- adapter item/club_response: shape_club_response excludes non-player kinds
  (ShapeStats.excluded_non_player); ItemIdentityResolver::kind_of default=Player.
- host Fifa17IdentityResolver overrides kind_of to delegate to the catalog so
  /club excludes consumables/staff in production.
- import: Item gains cardsubtypeid/cardassetid/amount/contract; plan_non_player_definitions
  (resourceId-grouped, subtype-consistency gated); emit_content writes non-player
  defs + catalog kind + manifest; apply mints owned instances via owned_item_id.

Real profile 33068179: 1962 players + 20 non-player = 1982 owned; 18 non-player
defs (16 consumable + 2 staff, dup resourceIds shared); 0 deferred non-player; 0 blockers.
