chore(deps): bump gravity-reth to acc45884 (rocksdb durability fix)

[nekomoto911]

What

Bump the gravity-reth git dependency:

• 41c0b7092ad578abcfb59b3aeb0ce9ec43f5fcf7 → acc458846c2f1fc684fa4344cf02ae9488efd252

Updates bin/gravity_node/Cargo.toml and the regenerated Cargo.lock. No SDK source changes.

Why

Pulls in gravity-reth#340 — a RocksDB durability fix. The rev range is exactly one commit ahead (ahead 1, behind 0); this bump introduces #340 and nothing else.

provider_rw.commit() called rocksdb::DB::write() without fdatasync(). With wal_bytes_per_sync=4MB, the low-traffic account_db/storage_db could go 2000+ blocks without syncing, risking large trie data loss on power failure and a state-root mismatch panic during consensus re-execution after a crash.

The fix:

1. All write() calls in commit_view() use write_opt(sync=true) — every commit() is fsync-durable before returning.
2. Disable pipelined write and drop wal_bytes_per_sync (redundant with per-commit sync).
3. Recovery always re-checks every stage checkpoint (no early return), repairing only stages that are behind.
