feat(surface-elo): getSurfaceEloMap reads from canonical

Browse source 
Switch the tennis simulator's Elo source from the per-window table
to the canonical participant_surface_elos via season_participants.participant_id.
Map key stays season_participant.id so the simulator's call pattern is unchanged.

Other functions in this file still read/write the per-window table
(seasonParticipantSurfaceElos). They back the old admin surface-elo page
and are removed in Phase 4 after the canonical admin flow replaces them.
