Correct Handling of Misconfiguration for Multiple Disks on Same Filesystem Path

Why it matters

This feature addresses the issue where ClickHouse could misbehave or encounter errors if multiple configured disks share the same underlying filesystem path. It improves stability and correctness by detecting and properly managing such misconfigurations, preventing potential data integrity problems or runtime conflicts.

How to use it

No special action is required by users to enable this fix. Users should ensure their disks configuration in storage.xml or server settings does not assign the same path to multiple disks. The system will now correctly handle or report cases where this misconfiguration occurs.
