Ledger Filecoin Coin integration

// Returns the best known block from the Filecoin REST API.
// The /network/status endpoint returns current_block_identifier which is the
// best (non-finalized) tip. Finality on Filecoin is probabilistic; the bridge
// already applies a 1200-block safe-delta in getAccountShape. We follow the
// same convention and let callers handle the safety delta if needed.
