style: apply spotless across the reactor

Ran `mvn spotless:apply` at the repo root. Reformatting affects:

- The moved doc-ai integration tests under integration-tests/spring
  (five files): minor line-break normalization introduced during the
  cds-feature-sap-document-ai import.
- One pre-existing formatting nit in
  cds-feature-ai-core/.../MockAICoreApiHandler.java that the previous
  runs of spotless never caught because the spotless check phase is
  gated by `${spotless.check.skip}` (default true) in the root pom.

No functional changes; unit and integration tests still pass.
