The error of the hooks should be passed to the controllers in a more explicit way, and reflect in the Status of the CRs

[allenxu404]

Sync with @anshulahuja98, this PR solely adds the "hooksAttempted" and "hooksFailed" fields to backup/restore CR to provide initial hook execution metadata. Tracking additional details like hook error information and skipped hooks can be supported in the future via a separate follow-up effort.

Once this PR is merged, I will create a new issue to track these potential enhancements.
