fix: address cursor bot review feedback

1. Fix Hunyuan provider never showing as configured
   - Add HUNYUAN_CONFIGURED placeholder when credentials provided

2. Fix configured status ignoring missing credentials
   - Bedrock: Check access key/secret or bearer token before marking configured
   - Vertex: Check auth key and service name before marking configured
   - Add similar checks for Cloudflare and DeepL providers

3. Fix multi-line JSON input issue for Vertex
   - Change from direct JSON paste to file path input
   - Read and compact JSON file content to single line
