feat(kb): add rename and delete knowledge base

- kb_list.dspy: add per-card rename (popup form) and delete (confirm+cascade) buttons
- rename_kb_form.dspy: popup form with name + description fields
- rename_kb.dspy: UPDATE knowledge_bases handler
- delete_kb.dspy: cascade delete (docs, chunks, media_tags, tags, files) handler
