Enable 5 lines of Sidekiq backtrace lines to aid in debugging

Closes #27626

See merge request !13813

Customers often have Sidekiq jobs that failed without much context. Without
Sentry, there's no way to tell where these exceptions were hit. Adding
in additional lines adds a bit more Redis storage overhead. This commit
adds in backtrace logging for workers that delete groups/projects and
import/export projects.

Closes #27626

Add an option to list only archived projects

Closes #35994

See merge request !13492

For some old merge requests, we don't have enough information to figure out the
old blob and the new blob for the file. This means that we can't highlight the
diff correctly, but we can still display it without highlighting.

Fix inconsistent number of branches when remote branches are present

Closes #36934

See merge request !13784

Users of project mirrors would see that the number of branches did not
match the number in the branch dropdown because remote branches were
counted when Rugged was in use. With Gitaly, only local branches
are counted.
