See merge request gitlab-org/gitlab-ce!17710

The concurrency issue originates from inserts on
`user_interacted_projects` from the app while running the post-deploy
migration.

This change comes with a strategy to lock the table while removing
duplicates and creating the unique index (and similar for FK
constraints).

Also, we'll have a non-unique index until the post-deploy migration is
finished to speed up queries during that time.

Closes #44205.

Breadcrumb on Admin Runner page

Closes #43717

See merge request gitlab-org/gitlab-ce!17431

When importing from a GitLab archive, an admin can carry over the
assignations. Other users can not.

When a regular user is importing an issue with multiple assignees, the
assignee is replaced with the current user, meaning we would try to
insert current user as an assignee multiple times.

By filtering the array before storing it, the import becomes more
robust.
