samples: fix AnonRequestMatcher case sensitivity and BigDataH2Service README

- AnonRequestMatcher.matches(): use toLowerCase() so both /services/loginService
  and /services/LoginService bypass the JWT filter; Axis2 URL routing is case-
  sensitive but callers may vary case
- springbootdemo-tomcat11/README.md: correct BigDataH2Service curl example to use
  required fields datasetId + datasetSize (bytes) instead of numRecords; add note
  on processing path thresholds and response fields

Tested with Java 25 + Tomcat 11.0.20.

+Required fields: `datasetId` (non-empty string) and `datasetSize` (bytes). Size determines
+processing path: <10MB → standard, 10–50MB → multiplexing, >50MB → streaming.

 ```bash
 curl -s -X POST http://localhost:8080/axis2-json-api/services/BigDataH2Service \

 ```
 
+Response includes `processedRecordCount`, `http2Optimized`, `memoryOptimized`, and (for <10MB
+datasets) a `processedRecords` array.
