Add link to customer portal from license dashboard

See merge request gitlab-org/gitlab!30330

Rails silently casts NULL `lock_version` values to 0 while doing
optimistic locking, which causes false stale object exceptions. We had a
monkey patch that would change it to check for [NULL, 0] but want to
avoid monkey-patching if possible, which means we need to clean up our
database values.

Query for vulnerability history

See merge request gitlab-org/gitlab!27052

Adds Vulnerability.count_by_day_and_severity. This method takes an
integer and returns vulnerability counts grouped by severity for that
number of days before the current day. It does not return rows when
there are no vulnerabilities for a day and severity.

The count does not include dismissed or resolved vulnerabilities.

This work is the first step towards moving the group security dashboard
history chart to first class vulnerabilities, and hopefully improving
its performance.
