Use gRPC instead of JSON-RPC for Write API in sui-indexer-alt-jsonrpc

Replace the JSON-RPC HTTP client delegation with gRPC calls for
executeTransactionBlock and dryRunTransactionBlock. The Write module now
uses FullnodeClient from sui-indexer-alt-reader, which communicates with
the fullnode via TransactionExecutionService gRPC.

- Add configurable read_mask parameter to FullnodeClient's
  execute_transaction and simulate_transaction methods
- Add --fullnode-grpc-url flag (separate from existing --fullnode-rpc-url
  which remains for DelegationGovernance JSON-RPC delegation)
- Implement proto-to-JSON-RPC response conversion for effects, events,
  balance changes, and object changes
- Build dynamic FieldMask based on SuiTransactionBlockResponseOptions
