Test job-profile revocation, completing the routes.ts sweep

The job-profile surface had no API test at all. The DELETE is the one that
matters: without its existence check it answers 200 "revoked" for a job that
never existed, so an operator revoking an agent's access is TOLD it worked
while nothing happened. For a revocation that is the worst available answer.
Revoking twice is asserted too, since a second success is how the false
positive shows itself.

routes.ts now sweeps to zero survivors across all 85 mutants under the
refusal-based selection, up from 30 mutants under the old vocabulary rule.
