Add prune_rocksdb_state to VM for pruning historic storage entries

[Copilot]

Adds a mechanism to prune historic state from storage maps (e.g. authority signatures, batch certificates) via the VM's sequential operation queue, preventing concurrent storage conflicts during pruning.

Changes

• SequentialOperation / SequentialOperationResult — new PruneRocksDBState variant; dispatched in start_sequential_queue
• VM::prune_rocksdb_state<S, T, V> — public method accepting any Map-implementing store and a key iterator; executes deletion sequentially
• BlockStore — exposes authority_map() and certificate_map() as public getters so callers can obtain the map handle to pass to prune_rocksdb_state

Usage

// Prune authority data for blocks older than 100 rounds
let old_hashes: Vec<_> = (0..=cutoff_height)
    .filter_map(|h| vm.block_store().get_block_hash(h).ok().flatten())
    .collect();

let authority_map = vm.block_store().authority_map().clone();
vm.prune_rocksdb_state(authority_map, old_hashes);

The method works with any Map implementation (MemoryMap, DataMap/RocksDB), so it is not restricted to the rocks feature. Two tests are included: a lightweight unit test using MemoryMap (no parameter download required), and a feature-gated integration test that verifies authority data is pruned while transactions remain intact.
