revert(balances): keep trackTokens operationId camelCase

The track_tokens route path is already snake_case (correct). operationId/SDK method names are camelCase across all ~40 routes (batchTrack, getOrCreateCustomer, redeemReferralCode...); Speakeasy emits the override verbatim, so snake_case here produced a lone track_tokens SDK method. Reverts bd41bde10.
