feat(analysis): scaffold chess analysis microservice (NCS-71)

Add new `modules/analysis` Quarkus microservice that proxies chess-api.com
to provide position analysis endpoints for the frontend.

- NCS-95: Scaffold analysis module with build.gradle.kts, application.yml,
  Jackson config, and native reflection registration
- NCS-96: Implement POST /api/analysis/position endpoint wrapping chess-api.com
  (ChessApiClient, AnalysisService, AnalysisResource, error handling)
- NCS-97: 13 unit/integration tests covering service logic and REST layer
  (AnalysisServiceTest, AnalysisResourceTest)
