BATCH_TX_LIMIT = 100

Maximum number of (target, amount) pairs that can be included in a single batch_fund_c_address contract call. Matches the MAX_BATCH_SIZE constant enforced on-chain (100).

When OnboardingBridgeSDK.batchFundCAddresses is called with more entries than this limit, it automatically splits the list into chunks of this size and submits one transaction per chunk.
