feat(storage): wire RocksDB into DB Provider And Historical Provider [3/3]

[yongkangc]

Summary

Complete RocksDB integration for history tables by wiring everything together. Closes #20388

This is PR 3/3 of a stacked PR series that splits #20412 for easier review.

Depends on: #20543 → #20542

Review focus

This is where behavior changes. Key areas:

1. Correctness: Do RocksDB history lookups match MDBX semantics?
2. Batch handling: Is the shared batch + last-shard cache correct?
3. Deduplication: Unwind uses dedup for RocksDB's "last write wins" semantics

Changes

EitherWriter / EitherReader

• Add account_history_info() and storage_history_info() methods to EitherReader
• Add read_account_history_shards() and read_storage_history_shards() methods
• Change RocksDB variant to borrow batch (&mut RocksDBBatch) for shared batch commits

HistoricalStateProviderRef

• Update account_history_lookup() to use EitherReader with RocksDB support
• Update storage_history_lookup() to use EitherReader with RocksDB support
• Add RocksDBProviderFactory + StorageSettingsCache + NodePrimitivesProvider trait bounds

DatabaseProvider

• Add pending_rocks_batch field for shared RocksDB batch
• Add pending_history_index_last_shards cache for read-modify-write operations
• Add append_account_history_index_rocksdb() and append_storage_history_index_rocksdb()
• Add unwind_account_history_indices_rocksdb() and unwind_storage_history_indices_rocksdb()
• Update HistoryWriter impl to route to RocksDB when configured
• Flush RocksDB batch on commit()

tx_lookup.rs

• Wire EitherWriter for transaction hash numbers
