fix: resolve actions commit status permission per repository (#38977)

Various pages did not display the correct action run list tooltips. Fix
those tooltips like here on the `/pulls` page:

`ctx.Repo.Permission` is the zero value outside a repository route, so
on `/pulls`, `/issues`, `/notifications/subscriptions` and the dashboard
repo list the commit status "Details" link was always stripped. The live
job status is looked up from that target URL, so running checks also
rendered as a static pending dot instead of a spinner.

Resolve the Actions unit permission per repository instead.

Also drops the releases page's gate on *loading* statuses, which hid
external CI results from anyone without Actions read; it now loads them
and hides only the URL, like every other page.
