## Summary
Fixes#37252
The `/api/v1/repos/{owner}/{repo}/actions/runs` endpoint was returning
`event: "push"` for workflow runs triggered by `schedule:` (cron),
instead
of `event: "schedule"`.
## Root Cause
`ActionRun` has two separate fields:
- `Event` — the workflow registration event (e.g. `push`, set when the
workflow file was first pushed)
- `TriggerEvent` — the actual event that triggered the run (e.g.
`schedule`)
`ToActionWorkflowRun` in `services/convert/action.go` was serializing
`run.Event` into the API response instead of `run.TriggerEvent`, causing
scheduled runs to be indistinguishable from push events via the API.
This was already asymmetric — the tasks/jobs API correctly used
`TriggerEvent`.
## Fix
Changed `ToActionWorkflowRun` to use `run.TriggerEvent` for the `event`
field in the API response, consistent with how the jobs API works.
## Before
`event: "push"` returned for all scheduled runs:

/>
## After
`event: "schedule"` correctly returned for scheduled runs:

/>
## Testing
- Added unit test `TestToActionWorkflowRun_UsesTriggerEvent` in
`services/convert/action_test.go` that explicitly verifies the API
returns `TriggerEvent` and not `Event` for a scheduled run.
- Manually verified via the API against a live Gitea instance with a
`cron: "* * * * *"` workflow.
