fix(admin): tune chat params, add Training sidebar link, fix reporting API keys

- Reduce chat history from 10 to 6 messages to fit context window
- Lower num_predict from 8192 to 2048 for faster responses
- Add Training module link to SDK sidebar navigation
- Add snake_case to camelCase key transformation for reporting API
  (Go backend returns snake_case, TypeScript expects camelCase)
