Issue:
- Restore checkpoint confirmation dialog (dangerModal) was hidden behind checkpoint management modal
- z-index of dangerModal (1000) was same as checkpointModal, causing layering issues
Solution:
- Increased z-index of .modal (dangerModal) from 1000 to 9999
- Now危险操作 confirmation dialog always appears on top of other modals
- Users can now properly see and interact with restore confirmation
This ensures critical operation confirmations are always visible and accessible.
