Similar to how some other parts of the web UI support a `/latest` path
to directly go to the latest of a certain thing, let the Actions web UI
do the same: `/{owner}/{repo}/actions/runs/latest` will redirect to the
latest run, if there's one available.
Fixes gitea#27991.

Code cleanup in the actions.ViewLatest route handler
Based on feedback received after the feature was merged, use
`ctx.NotFound` and `ctx.ServerError`, and drop the use of the
unnecessary `ctx.Written()`.
