[chore] Bump local LLM glm-5→glm-5.2 + swap Ollama fleet defaults off minimax

- llm_catalog: OLLAMA_DEFAULT_MODEL minimax-m3:cloud → kimi-k2.7-code:cloud;
  role defaults kimi-k2.6→kimi-k2.7-code, developer minimax→kimi, product_owner/
  ceo kimi→glm-5.2, documenter glm→kimi; GLM 5.1→5.2 comment fix.
- config + .env.example + docker-compose{.yml,.yaml,.registry.yml} + docs +
  memory_distiller + optimal_brain: glm-5:cloud → glm-5.2:cloud.
- panel ai-routing-card: typed SelfHostedModel/boolean annotations; drop the
  stale "Minimax M3 default" string (default is now catalog-driven).
- tests: glm-5:cloud → glm-5.2:cloud in pricing + rate-limit-retry fixtures.
