fix(lock): address review comments for lock feature

1. Store batchToggleEnabled now uses continue to skip locked blocks
   entirely, matching database operation behavior

2. Copilot add operation now checks if parent container is locked
   before adding nested nodes (defensive check for consistency)

3. Remove unused filterUnprotectedEdges function
