Fix dead oversized-video link and stop exposing the platform limit to readers

build_oversized_video_note linked to the video's own VK page (with an
access_key suffix), which 404s for viewers without a VK session - reported
as "такой страницы нет" on a real post. Point at the wall post instead
(vk_url), same as build_media_unavailable_note already does, since that
always resolves.

Also dropped "Видео слишком большое для платформы" from the visible text -
subscribers don't need to know MAX has a 250MB cap, that's an internal
implementation detail, not something worth surfacing in a public post.
