Fix MCP JSON Schema validation for tools/list endpoint 

- Fix inputSchema properties to use quoted string keys for proper JSON Schema format
- Remove debug logging added for Accept header troubleshooting
- Remove unnecessary tools/list workaround in mcp#ToolsCall service
- The properties field in inputSchema must be a record/object, not an array
- All 6 tool schemas now properly defined with string keys: "path", "action", "renderMode", "parameters", "query", "name", "arguments"
