fix(deps): bump @sasjs/core to 5.2.7

Brings in the mv_jobflow JSON-escape fix (prevents jobExecution 400s
for job arguments containing quotes or CR/LF) and the graceful
handling of canceled jobs in mv_getjoblog / mv_getjobresult (a
canceled child no longer aborts the calling program when its log or
result is unavailable).  Verified against a live Viya 2026.07 estate:
the full SAS test suite passes with these macros sourced from core.
