feat(wal): optimize the start-up and shutdown of WAL

[CLFutureX]

Motivation ： As a core component of AutoMQ that is closely related to memory resources, the initialization and termination processes of WAL must ensure a high degree of robustness. However, there are currently some flaws in these processes that fail to achieve a complete operational loop. This means that during the startup and shutdown processes, all relevant resources may not be properly handled, which can affect the stability and reliability of the system. It is necessary to further optimize these processes to ensure they can manage memory resources seamlessly from start to finish, avoiding potential resource leaks or other issues.
