refactor: remove dangerous, AI proxy, and API key tools from MCP server

- Remove delete_all_notes, 11 AI proxy tools, 3 API key management tools
- Clean up unused imports (auth helpers, resolveUser, clearAuthCaches)
- Remove fetchWithTimeout helper and appBaseUrl option (no longer needed)
- Update tool counts in health endpoint and startup banner (37 → 22 tools)
- Keep only CRUD notes/notebooks/labels + reminders + search/export/import
