[FEATURE] Copy live dbs

[tac0turtle]

Problem to solve

We would like to have a solution to copy live dbs instead of having to stop the node in order to take snapshots. this is supported with reth via mdbx_copy, we still need to understand how to predict the block height in the copy. With badger DB we will need to extend the store to have a cli that allows us to copy a specific height.

If we are unable to predict the mdbx_copy height we can do a flow where the user first copies the reth database then figures out the height and then dumps that height from ev-node. this would make things simple.

Proposed solution or feature

Add a backup store method to allow to backup specific heights to store. This should be done via a cli command while the node is running.
