fix(lock): ensure consistent behavior across all UIs

Block Menu, Editor, Action Bar now all have identical behavior:
- Enable/Disable: disabled when locked OR parent locked
- Flip Handles: disabled when locked OR parent locked
- Delete: disabled when locked OR parent locked
- Remove from Subflow: disabled when locked OR parent locked
- Lock: always available for admins
- Unlock: disabled when parent is locked (unlock parent first)
