feat(tenant): make monitoring parse & compliance judge models configurable

Replace the hardcoded doubao-lite model used for monitoring answer
parsing and compliance LLM judging with configurable values, resolved
from config with env overrides and a legacy default fallback.

- Add llm.monitoring_answer_parse_model and compliance.llm_judge_model
  to config struct, env overrides, and all config files
- Thread the resolved model through MonitoringCallbackService via a
  ConfigProvider and into parseMonitoringAnswerWithLLM
- Pass compliance.llm_judge_model into the review-job LLM request
