Claim unlocked block rewards

post/collateral/rewards/claimapi_key

Sweep every unlocked reward box to this wallet's primary address (EIP-3 index 0), batching boxes into as few transactions as possible. Dust is consolidated, never dropped.

A sweep that broadcasts nothing returns an error status rather than an empty 200, so a result with no claims is never ambiguous.
