testapp: pace request dispatch in batches, report progress counters

Give the tester control over the load the reservation bench puts on the
license service and the license server: --batch-size <N> dispatches the
-j jobs in batches of N, --batch-delay <ms> apart (giving either option
alone defaults the other: 1000 ms delay, batch size 100). The default
behavior is unchanged - all jobs still start within about one second.
Options now accept both the "--option value" and "--option=value" forms.

The bench also no longer goes silent while dispatching: previously the
event loop fired every due job start before processing a single result,
so a large -j produced no output until all jobs were constructed, and
then a sudden flood of accumulated results. The start events are now
fired in bounded slices (64, mirroring the service's event batch bound),
interleaved with result processing, so progress prints from the first
completions onward while dispatching continues.

Every finished job reports the round's progress next to its id:

  [123 Done] [Undispatched(N) dispatched(N) completed(Failed: N, Success: N) total(N)]

with the same counters appended to the failure prints. The completed
counter reports every job that reached its end state, split into
failed and successful outcomes.

client: fail fast when connect fails on exhausted local resources

watching loop (3154095f) retried every connect failure until deadline,
including EADDRNOTAVAIL/EMFILE/ENOBUFS. those are local host resources:
retrying cannot fix them, and a single-threaded caller whose own
connections hold the ports waits on itself (30k bench: 30s burned per
job, releases never ran, ports never freed).

fix: TcpClient::connectFailedOnExhaustedResources() exposes the
existing classification (connect failure hint is non-empty exactly for
these errnos), licenseclient init gives up immediately on it in both
the initial attempt and the watching-loop retry. tests added.

testapp: never block the dispatch thread on init

startReservation used init(30): a failing connect parked the single
dispatch/result thread up to 30s per job, queued results and releases
never ran, 30k bench froze (0 results consumed).

fix: init(0) + failed starts requeued on the timeline 1s apart, max 30
attempts. dispatch stays non-blocking, results/releases drain between
attempts and free the resources the waiting starts need.
