feat: integrate ONLYOFFICE docspace-mcp v3.1.0

- Updated CloneVendorRepos.sh to use official ONLYOFFICE/docspace-mcp
  repository instead of ahujasid/docspace-mcp (which was outdated)
- Successfully built and validated docspace-mcp Docker container (236MB)
- Created wrapper script mcp-docspace-wrapper.sh with environment
  variables for DOCSPACE_HOST and DOCSPACE_TOKEN
- Added docspace MCP configuration to crush.json
- Updated STATUS.md with working status for docspace-mcp

MCP handshake test confirmed server responds correctly:
- Protocol version: 2024-11-05
- Server: @onlyoffice/docspace-mcp v3.1.0
- Capabilities: tools

Also documented blocked MCPs in STATUS.md:
- matomo-mcp: vendor repo does not exist (404)
- discourse-mcp: vendor repo exists but is empty (no commits)
