When reviewing an MR commit by commit, there are `Prev` and `Next`
buttons next to the commit message to jump to the neighbor
commits. These are helpful, but they slide outside of view when
scrolling to the bottom.

These buttons were initially introduced in [1].

This changes moves these buttons to the sticky Merge Request controls
bar. This bar remains visible at all times, making the neighbor commit
buttons accessible even when scrolled to the bottom.

Fix force_random_password option in Users API

See merge request gitlab-org/gitlab!57751

Previously the API did not correctly handle the force_random_password
option. It was not being treated as one of the 3 viable password-
setting options. This adds it as the 3rd, and fixes the test coverage,
which was not properly testing this use case.
