Add bulk copy and delete all tags for node replacement workflow

When replacing a node device, users can now:
- Copy All: Copy all tags to a new node (skips existing tags)
- Delete All: Remove all tags from a node after migration

New API endpoints:
- POST /api/v1/nodes/{pk}/tags/copy-to/{dest_pk}
- DELETE /api/v1/nodes/{pk}/tags
