Fix moving issues API failing when text includes commit URLs

Closes #66666

See merge request gitlab-org/gitlab-ce!32317

When a issue is moved from one project to another, all associated
Markdown text is rewritten in the context of the new project. If the
note contained a link to a commit URL, `CommitRewriter#rewrite` would
fail because `Commit#link_reference_pattern` would match `nil` `commit`
values in the HTML generated from the Markdown. These `nil` values were
passed along to `Project#commits_by` because `Commit#reference_valid?`
was always returning `true`.

To prevent this issue from happening, we tighten up the check for
`Commit#reference_valid?` to look for valid SHA values.

CE backport for gitlab-org/gitlab-ee!15433 (Expose DesignType#notes_count in GraphQL)

See merge request gitlab-org/gitlab-ce!32037

Notes call `#after_note_created` and `#after_note_destroyed` on their
noteable in callbacks, so the noteable can perform tasks particular to
them, like cache expiry.

This is in preparation of the EE-specific class
`DesignManagement::Design` clearing its `user_notes_count` cache when
its note are created or destroyed.

Closes #60141

The file title sometimes overflows its container, which has the same
border-radius. By always rounding the file title, the overflow never
happens, so the corners always look correct.

Everywhere else there are file diffs, there is a top border to complete
the full border around the file.
