Add player cluster + labeling mutation types

Schema additions for the per-video player labeling UI:
  * `PlayerClusterGQL` / `PlayerClusterShotGQL` — read shape.
  * `FinalizePlayerAssignmentsInput` + `ClusterAssignmentInput` +
    `ShotMoveInput` — write shape.
  * Query: `videoPlayerClusters(videoId)`.
  * Mutation: `finalizePlayerAssignments(input)`.

Generated by `just gql` from the backend type definitions in
`railbird/datatypes/gql/shooter.py` and resolvers in
`railbird/server/resolvers/shooter.py`.
