testapp: drive the reservation bench event-driven, not thread-per-job

Don't spawn a thread per reservation as that will choke the system
when simulating heave parallel usage (e.g. 10k+ reservations).

Rework the testapp to be event-driven from a single thread:

- reserve() is already asynchronous: TestApp::startReservation()
  (replacing the blocking requestLicense()) starts the reservation
  and reports the result through a callback.
- The bench keeps a timeline (min-heap) of job start times
  (preserving the randomized ~1s startup spread) and of simulated
  work-completion deadlines, instead of parking a thread in sleep
  per job. Results arrive through a queue fed by the clients'
  callback threads.
- A job's first callback decides its benchmark result; later renewal
  or revocation notifications are ignored. The old code had a latent
  bug here: a heartbeat renewal callback wrote to the bench thread's
  dead stack variable ('success') after requestLicense() returned.
