Repository trust preview before install

[diprapaul700078-ui]

Describe your suggested feature

Before importing a repository, show a short preview with host, plugin count, language support, last update time, NSFW flag, and whether it is local or remote. That would reduce accidental installs and help users judge trust faster.
