fix(jobs): nest jobs router under /api/jobs to match gateway routing

The gateway forwards /api/jobs unmodified to the jobs service, but the
service registered its routes at bare /jobs with no prefix — every
other service (companies, users) nests under /api/<service> to match.
This made the public job listing endpoint unreachable (404) through
the gateway on test111.
