The runner-listing API endpoints (`admin`, `org`, `user`, `repo`, and
`shared`) return runners in a non-deterministic order across pages. When
paging through runners, some runners from page 1 could reappear on page
2 (and others get skipped entirely).
The cause is in `FindRunnerOptions.ToOrders()`. Most sort modes order by
a **non-unique** column only:
- default / `online` / `offline` → `last_online`
- `alphabetically` / `reversealphabetically` → `name`
When multiple runners tie on the sort key (e.g. every offline runner
shares `last_online = 0`, or two runners have the same name), the
database is free to return the tied rows in any order between separate
queries. Combined with `LIMIT`/`OFFSET` pagination, this means the same
runner can land on more than one page.
## Fix
Append the unique primary key `id` as a stable tiebreaker to each
non-unique sort order:
The `newest`/`oldest` modes already sort by the unique `id`, so they are
left unchanged.
