Say out loud when she gives up instead of dropping the request

An unclear answer used to end the request on the spot. Now she re-asks the same
question while attempts remain, and when they run out she says
"Прости, я не поняла. Скажи, пожалуйста, по-другому." — silence would leave him
thinking it was handled. Same reply when the missing slot has no question to
ask, and as a floor in finishClarified so an empty reply can never ship.

Tests: three questions allowed, the fourth gives up out loud, the cap is
configurable, and a restated time is the one that lands.
