feat(agent-documents): replace page navigation with right-side drawer

- Create AgentDocumentDrawer.vue: right-side drawer with document list + detail view
- AgentSidebar: change document NuxtLink to button emitting showDocuments
- AgentToolbar: change document NuxtLink to button emitting showDocuments
- AgentChatArea: forward showDocuments event from toolbar to page
- Chat page: wire showDocumentDrawer state + render AgentDocumentDrawer

Drawer features:
- List view with type filter (all/document/memory) + search
- Detail view with markdown rendering via AgentMarkdown
- Slide-in transition + overlay backdrop
- Teleport to body for proper z-index stacking
