feat(rpc): return flashblock state for pending block queries

[fridrik01]

This PR overrides local_pending_state() in LoadPendingBlock to return flashblock state for pending block tag queries. This enables all state-reading RPC methods (eth_getBalance, eth_getTransactionCount, etc.) to return in-progress flashblock data while "latest" continues to return finalized state

i believe the better approach is to override the impl of

impl<N, Rpc> LoadPendingBlock for BerachainApi<N, Rpc>

e.g. see https://github.com/paradigmxyz/reth/blob/5b21aa18ce0d6a3693fc2606b9452c03374c598a/crates/optimism/rpc/src/eth/pending_block.rs#L41

this will then implicitly propagate to method like get_balance
