feat(mcp): add all 4 note types, translate N8N docs to English, add N8N workflow examples

- tools.js: expose type enum ['text','markdown','richtext','checklist'] in create_note & update_note
  - default changed from 'text' to 'richtext' (matches Prisma schema)
  - isMarkdown marked as deprecated in favour of type='markdown'
- N8N-CONFIG.md: full French → English translation
- N8N-WORKFLOWS.md: full French → English translation
- N8N-EXAMPLES.md: new comprehensive examples for all 22 MCP tools + workflow patterns
- n8n-workflow-mcp-reminder-bot.json: cron → get_due_reminders → Telegram → mark done
- n8n-workflow-mcp-email-to-note.json: IMAP → create_note → urgent Slack alert
- n8n-workflow-mcp-daily-digest.json: 8AM cron → notes + reminders digest → save + Slack
- n8n-workflow-mcp-webhook-to-note.json: universal webhook → create_note → respond
- notebooks-list.tsx: fix truncated notebook names (pe-24→pe-14), replace hover overlay with Tooltip
