feat(api): add sort and order query parameters to job list endpoints (#37672)

Adds `sort` and `order` query parameters to all action job list API
endpoints (`/admin/actions/jobs`, `/repos/{owner}/{repo}/actions/jobs`,
`/repos/{owner}/{repo}/actions/runs/{run}/jobs`, `/user/actions/jobs`),
following the existing `OrderByMap` pattern used by repo/user search
endpoints.

- Default is `id` / `asc` (backwards compatible — matches previous DB
natural order)
- Only `id` sort field for now; the map is extensible for future fields
- Returns 422 for invalid sort/order values
- `ToOrders()` returns empty string when `OrderBy` is unset, so internal
callers (webhook dispatch, concurrency checks) are unaffected

Closes: #37666
Supersedes: #37667
