Downgrade bcrypt to v3.1.12

See merge request gitlab-org/gitlab!18828

v3.1.13 doesn't work compile on ARM platforms:
https://github.com/codahale/bcrypt-ruby/issues/201

We can revert the change in
https://gitlab.com/gitlab-org/gitlab/merge_requests/18225, since this
wasn't an essential update.

Instead of 1,000,000 characters, we increased the limit to 1 megabyte
(https://gitlab.com/gitlab-org/gitlab/merge_requests/18605), which is
1,048,576 bytes.

Closes https://gitlab.com/gitlab-org/gitlab/issues/34172

On GitLab.com, we observed statement timeouts counting the number of
active users minus guests:
https://gitlab.com/gitlab-org/gitlab/issues/32287.

To work around this problem, hide the license breakdown if the estimate
number of users exceeds 100,000.

The "Explore snippets" page loads very slowly with a large number of
snippets, due to the complexity of the authorization checks for project
snippets.

Since project snippets are of limited interest on the explore page, we
can restrict the query to personal snippets which are visible to the
current user.

We're also replacing the index on `snippets.project_id` with a combined
index on `(project_id, visibility_level)` to further speed up these
queries.
