fix: complete MCP server validation and documentation

- Fixed penpot-mcp Dockerfile for monorepo build (added data/ copy)
- Fixed snipeit-mcp Dockerfile COPY path and entrypoint
- Completed validation of all pending MCP servers
- Updated STATUS.md with comprehensive validation results
- Added JOURNAL.md entry documenting session work

Validation summary:
- terraform-mcp: Working (MCP handshake validates)
- 6 servers require config/env vars (matomo, nextcloud, paperless, postizz, redmine)
- 6 servers have build/runtime issues (discourse, revas, snipeit, proxmox, penpot, mcp-ansible)
