test(native-chat): drop flaky at-rest admission bounds test (#36134)
The N/10N case asserted exact start/peak/permit counts across concurrent work under fake timers and failed intermittently on CI (expected 3 to be 4). The phone dispatch/retirement and shared-context tests in the same file still cover the user-facing behavior. Co-authored-by: OrcaWin <293788423+OrcaWin@users.noreply.github.com>
