Subject: [PATCH] ci: gzip junit results in SHARED_DIR to avoid Secret size
 limit

Gzip junit XML before writing to SHARED_DIR to stay under the
Kubernetes Secret 1 MiB size limit. Raw junit XML can exceed this
when coverage <property> tags and many test cases are present. XML
compresses ~10-15x with gzip, keeping even large files well under
the limit.

Also adds a safety check that removes the gzipped file if it still
exceeds 800 KB after compression, and validates the source file
exists before attempting the copy.

The data-router step in openshift/release already handles both .gz
and plain .xml formats (openshift/release#81313).
