[v15.0/forgejo] fix: in actions_service cancelJobsForRun is bugous use killRun instead (#12492)

The conflict resolution is explained in the "Conflict" section of the commit message. I used `cherry-pick -x`. Here is the conflict for information (simple one).

```

**Backport:** https://codeberg.org/forgejo/forgejo/pulls/12366

The cancelJobsForRun function is redundant with the killRun function
and has bugs:

- It does not use a transaction and may fail in a non-recoverable way
- It does not update the commit status of the run
- It does not set NeedRemoval to false if needed

Remove the cancelJobsForRun function and use killRun instead (fixing
forgejo/forgejo#12386). Both calls are covered by existing tests:

- TestCancelPreviousJobs
- TestCancelPreviousWithConcurrencyGroup

A new integration test TestActionsPullRequestTrustPushCancel is added
to verify that the NeedApproval field is set to false whenever a run
is cancelled (fixing forgejo/forgejo#12350).

Closes forgejo/forgejo#12350
Closes forgejo/forgejo#12386

(cherry picked from commit b6af380324)

+When the author of a pull request is [denied the right to run Actions](https://forgejo.org/docs/next/user/actions/security-pull-request/) by clicking on the "Deny" button on the pull request trust management panel, the workflow runs created for all commits pushed to the pull request are cancelled. Before that, runs that were automatically cancelled because a newer commit was pushed to the pull request [were stuck in a state waiting for approval](https://codeberg.org/forgejo/forgejo/issues/12350).
