feat: complete Groq provider integration and add Kimi K2 model (#978)

* feat: complete Groq provider integration and add Kimi K2 model

- Add missing getRequiredApiKeyName() method to GroqProvider class
- Register GroqProvider in ai-services-unified.js PROVIDERS object
- Add Groq API key handling to config-manager.js (isApiKeySet and getMcpApiKeyStatus)
- Add GROQ_API_KEY to env.example with format hint
- Add moonshotai/kimi-k2-instruct model to Groq provider ($1/$3 per 1M tokens, 16k max)
- Fix import sorting for linting compliance
- Add GroqProvider mock to ai-services-unified tests

Fixes missing implementation pieces that prevented Groq provider from working.

* chore: improve changeset
