-- Multi-game support. Every profile (and therefore all of its downstream state,
-- which hangs off profiles(id) via profile_id / club_id foreign keys) is scoped to
-- a game. Bridges identify their game with the X-OpenFUT-Game request header.
--
-- Default 'fifa23' preserves the existing single-game behaviour: the current bridge
-- and the integration tests send no game header, so they keep operating on the same
-- (now fifa23-tagged) profile with zero behaviour change. The FIFA 17 bridge sends
-- X-OpenFUT-Game: fifa17 and therefore gets its own isolated profile/club/state.
--
-- Only profiles needs the column: get_active_profile becomes game-scoped, and because
-- all other tables reference a profile (directly via profile_id or via
-- club_id -> clubs.profile_id), scoping the active profile isolates the whole tree.
