fix(handlers): replace time.Sleep with explicit async drain in 1 test (issue #1264)

Issue #1264: CI/Platform(Go) tests flake under parallel CI load.
TestProxyA2A_AllowedSelf_SkipsAccessCheck uses time.Sleep(50ms) to wait
for goroutines launched by goAsync() — same pattern as the 4 tests fixed
in PR #1282. Replacing with handler.waitAsyncForTest() ensures deterministic
async completion regardless of runner speed/pressure.

Also fixes the sop-checklist test file (parse_directives tuple return
type mismatch) that was committed in broken state to PR #1284.
