Add suggestPositionShot schema types and operation

Mirrors the backend's position-play search: SuggestPositionShotInputGQL
(pot lock + target-area polygon), PositionSuggestionGQL /
PositionShotCandidateGQL / CueStrikeGQL, the Query field, and a
SuggestPositionShot operation with a shared candidate fragment. The
regenerated hooks also provide the result types the mobile app uses to
shape local (billsim) physics results.
