fix: improve handling of repo event not found

even if the repo event doesn't exist there may be many issues
and proposal that reference it so it makes sence to:
1. show the repo Menu with a count of proposals and issues
2. show the details within the address point
2. show the issues and proposals page with a warning

RepoPageWrapper stops overwriting all content with error
RepoHeader show warning
RepoDetails show basic details from address point and a warning
