fix: correct tool count (596), default English dashboard, clean up stale references

- Tool count corrected: 589→596 (was missing 4 OAuth + 4 system config tools)
- System tools: 17→24 (accurate count of @mcp.tool() functions)
- Dashboard defaults to English; Farsi only via ?lang=fa query param
- Updated across all files: README, CLAUDE.md, CONTRIBUTING, DOCKER_README,
  getting-started, CHANGELOG, endpoints config
- Removed remaining Phase references from server.py startup log
- Tests: 289 passing
