Fix Gemini CLI compatibility: Convert all Pydantic return types to Dict[str, Any]

- Fixed 10 tools to avoid / patterns in JSON schemas
- All tools now return Dict[str, Any] with .model_dump() applied
- Affected tools:
  * search_emsal_detailed_decisions
  * get_emsal_document_markdown
  * search_uyusmazlik_decisions
  * get_uyusmazlik_document_markdown_from_url
  * search_rekabet_kurumu_decisions
  * get_rekabet_kurumu_document
  * search_sayistay_unified
  * get_sayistay_document_unified
  * search_kvkk_decisions
  * get_kvkk_document_markdown
- Gemini CLI should now be able to load and use all MCP tools without schema validation errors
