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.

Issue:
- Object of type <class 'uuid.UUID'> is not JSON serializable error when creating checkpoints
- UUID objects in database records couldn't be serialized to JSON
Solution:
- Updated json_serializer function in create_checkpoint() to properly handle UUID types
- Added explicit isinstance check for uuid.UUID before checking for isoformat
- Ensures all UUID values are converted to strings before JSON serialization
This ensures checkpoints can be created successfully with all database data types.

Features:
- Create manual database checkpoints with descriptions
- List all available checkpoints with statistics
- Restore database from checkpoints (with dangerous operation warning)
- Delete unwanted checkpoints
- Frontend UI integrated into database admin panel
- JSON-based checkpoint storage in data/checkpoints/
Backend Changes:
- Added checkpoint management functions to licensing_repo.py:
* create_checkpoint() - backup all tables to JSON
* list_checkpoints() - enumerate checkpoint files
* restore_checkpoint() - restore from checkpoint
* delete_checkpoint() - remove checkpoint file
- Added 4 new API endpoints to v2.py:
* GET /admin/checkpoints - list checkpoints
* POST /admin/checkpoints - create checkpoint
* POST /admin/checkpoints/{id}/restore - restore checkpoint
* DELETE /admin/checkpoints/{id} - delete checkpoint
Frontend Changes (db_admin.html):
- Added step 5 "检查点管理" to navigation
- Created checkpoint management UI with forms and lists
- Added dangerous operation confirmation modal
- Integrated into existing breadcrumb navigation system
Safety Features:
- All dangerous operations require explicit confirmation
- Restore operations show warning about data loss
- Checkpoints include row counts and table statistics
- Timestamped checkpoint IDs for easy identification
