Evaluate cleanup operations in Stop method of WAL

he Stop method of the walForge is responsible for gracefully shutting down the Write-Ahead Log component. It currently handles stopping internal tickers, canceling the context, syncing the current segment file to disk, and closing the file. However there might be additional cleanup operations missing, which could lead to resource leaks, unpersisted state, or an inconsistent system state upon shutdown or subsequent restart. Refer below TODO in code

// TODO: See if we are missing any other cleanup operations.
