Get Division Pairing Matrix
How often each current champion policy shares a game with every other in this division.
Scoped to the division’s current champions (competing + is_champion memberships) so the grid
stays the size of the live roster instead of every policy that ever appeared in a round — the
latter is both O(policies^2) to build and huge to render. We fan the division’s rounds out to
their episodes (episode_requests) and read the seated policies (episode_request_policies),
restricted to champion policy versions. Two policies “played together” for each episode where
both sit in a non-filler seat; filler (“zombie”) seats are excluded so the fairness grid
reflects real entrants only. The diagonal (games_played) is each champion’s own distinct
non-filler episode count; a champion with no episodes yet is omitted entirely.

How often each policy shares a game with every other policy in a division.
policies is the shared ordering for both axes; cells carries only the
unordered upper-triangle pairs with a non-zero count (a<b by policy label
then id, matching the policies order), so the client renders a symmetric
grid. Filler ("zombie") seats are excluded so fairness reflects real
entrants only.
