Deducts effectivePrice of the bundle's price currency from the player and grants every reward in the bundle.

🚧

Idempotency

The Idempotency-Key header is required. Generate one key when the player taps "Buy" and send that same key on every retry of that tap, so a dropped response cannot charge the player twice. Use a fresh key for the next purchase.

After a successful purchase, re-fetch GET /player-rewards/brand/{brandId}/player/{playerId} so the player's balances reflect both the deduction and the granted reward. newBalance in the response covers the price currency only.
