Subject: [PATCH] feat(web): add markdown round-trip and replace textarea with
 Tiptap editor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add tiptap-markdown extension for markdown ↔ rich text conversion.
Update KnowledgeEditor to accept/emit markdown content. Replace
EntryEditor textarea with KnowledgeEditor (Tiptap WYSIWYG). Update
tests for the new editor component.

Content flow: markdown (stored) → Tiptap (editing) → markdown (saved).
The backend markdown → HTML rendering pipeline remains unchanged.

Implements TW-EDT-002.
