ci(hypatia-scan): drop timeout-minutes from the reusable-caller job

A job that uses a reusable workflow (jobs.<id>.uses) may not declare timeout-minutes — GitHub rejects the file as invalid ("Unexpected value 'uses'/'secrets'; Required property is missing: runs-on"), so the workflow never parsed and every run produced 0 jobs, at every pin. This is why nextgen-* stayed 0-jobs while eclexia/Axiom (no timeout-minutes) worked. Removing the line makes the caller valid; the reusable enforces its own per-job timeout.
