Выгрузка карты из памяти + фиксы столбца адресов

1) Карта выгружается (map.destroy()) через 2с после ухода в режим «График»
   — освобождает тайлы/canvas/GPU (~350–450 МБ); отменяется при возврате.
   Метод MapView.destroy() (сброс map/objectManager/initPromise/pending);
   в onModeChange сброс mapLoadedKey, иначе refreshMap короткозамыкал render и
   свежий ObjectManager оставался пустым.

2) MIN_LABEL_W 140→200 — три пилюли Город/Адрес/Код не обрезаются на узком
   столбце; container-query прячет подпись «Показывать» при ширине < 255px.

3) Правый/левый отступ 7px у содержимого строки (#timeline .vis-label .vis-inner,
   специфичность выше собственного padding vis-timeline) — адрес не липнет к
   границе столбца.
