VideoAssetController.java, backed by richer UploadSession metadata in src/main/java/org/example/videoclips/domain/UploadSession.java. The service now stores part size, part count, expiry, and
completion time, and returns them through src/main/java/org/example/videoclips/application/VideoAssetService.java. I also added a configurable media-type allowlist in src/main/java/org/example/
videoclips/config/VideoClippingProperties.java and reject unsupported uploads with 415 via src/main/java/org/example/videoclips/application/UnsupportedMediaTypeException.java and src/main/java/
org/example/videoclips/api/ApiExceptionHandler.java.
I also added adapter-level health visibility for operations. src/main/java/org/example/videoclips/observability/ObjectStorageHealthIndicator.java and src/main/java/org/example/videoclips/
observability/QueueHealthIndicator.java now expose basic readiness details through Actuator. Tests were extended in src/test/java/org/example/videoclips/api/VideoAssetControllerTest.java to cover
the upload-session read path and the unsupported-media-type case.
