fix: improve actions status icons and texts (#37206)

Action runs, jobs and steps have 8 statuses but the UI only showed 5
(from the commit status api) for the latter two. Align all 8 to GitHub
as closely as possible:

  - waiting — `octicon-circle` (hollow circle), gray
  - blocked — `octicon-blocked` (slashed circle), yellow
  - running — `gitea-running` (rotating spinner), yellow
  - cancelled — `octicon-stop` (gray), was `octicon-x` (red)

Descriptions also aligned with GitHub:

  - "Has started running" → "In progress"
  - "Has been cancelled" → "Cancelled after {dur}"
  - "Has been skipped" → "Skipped"

Fixes: https://github.com/go-gitea/gitea/issues/32228
