Activate include-sql-reporting profile so NiFi images ship QueryNiFiReportingTask

Summary

QueryNiFiReportingTask is missing from the NiFi images we ship. Upstream keeps nifi-sql-reporting-nar behind the non-default nifi-assembly profile include-sql-reporting, and our build does not activate it. The module itself is already compiled by our build, only the assembly inclusion is missing, so the fix is one profile name in nifi/Dockerfile.

Expected

QueryNiFiReportingTask is selectable as a Reporting Task in a NiFi Stacklet built from a stock SDP image.

Actual

The processor type does not exist; lib/ contains no nifi-sql-reporting-nar.

Workaround

Layer the upstream NAR onto the released image; no rebuild of NiFi needed. Example for
NiFi 2.7.2 from SDP 26.3.0:

FROM oci.stackable.tech/sdp/nifi:2.7.2-stackable26.3.0
USER 0
ADD --chown=1000:0 --chmod=660 \
  https://repo1.maven.org/maven2/org/apache/nifi/nifi-sql-reporting-nar/2.7.2/nifi-sql-reporting-nar-2.7.2.nar \
  /stackable/nifi/lib/
USER 1000

Open nifi/Dockerfile and find the nifi-assembly profile configuration. Activate the include-sql-reporting profile, then build a stock SDP NiFi image and verify that nifi-sql-reporting-nar appears under lib/ and QueryNiFiReportingTask is selectable as a Reporting Task.
