Subject: [PATCH] fix(dify): correct reranking_model JSON key in DifyRAG
 retrieval request

Fixed incorrect JSON key 'reranking_mode' to 'reranking_model' in DifyRAG retrieval request payload.
Also renamed variable from 'rerankingMode' to 'rerankingModel' for consistency.

Changes:
- DifyRAGClient.java: Changed 'reranking_mode' to 'reranking_model'
- DifyRAGClientTest.java: Updated test to use correct key name

Reference: Dify API expects 'reranking_model' for reranking configuration
