When you access Actions logs, there is a momentary render of a partially blank screen such as this:

This is caused by the `RepoActionView` Vue component having no data. It then performs a fetch to two APIs in parallel (shown here as `/0` and `/artifacts`) to retrieve the steps and artifacts for the action run, and then it renders the page.
And then, even if the job is complete and the user hasn't yet interacted to expand any logs, it performs the same API calls a second time.

This PR fixes both problems by:
- Injecting the initial data for the Action's steps & Artifacts into the initial page render, and using that data into the `RepoActionView` to serve as its initial data load.
- No longer unconditionally starting a second invocation of `loadJob` 1 second later, as the initial data can be used to determine whether the job is still running and requires an interval refresh.

### Tests
**WIP**
- I added test coverage for Go changes...
- [ ] in their respective `*_test.go` for unit tests.
- [x] in the `tests/integration` directory if it involves interactions with a live Forgejo server.
- I added test coverage for JavaScript changes...
- [x] in `web_src/js/*.test.js` if it can be unit tested.
- [ ] in `tests/e2e/*.test.e2e.js` if it requires interactions with a live Forgejo server (see also the [developer guide for JavaScript testing](https://codeberg.org/forgejo/forgejo/src/branch/forgejo/tests/e2e/README.md#end-to-end-tests)).
### Documentation
- [ ] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change.
- [x] I did not document these changes and I do not expect someone else to do it.
### Release notes
- [ ] I do not want this change to show in the release notes.
- [x] I want the title to show in the release notes with a link to this pull request.
- [ ] I want the content of the `release-notes/<pull request number>.md` to be be used for the release notes instead of the title.

Adds a new dropdown to the job logs, visible only when a job has been retried at least once:

When an older run attempt from the dropdown is selected, displays the older run's logs:

Context on implementation & design decisions:
- It is important that when a URL from an Action's log is shared, the person on the other side sees the exact same logs that were being viewed. For this reason, all log views are automatically redirected to a fully-qualified URL (including the *run*, *job*, and *attempt*), so that when they are shared there is a guarantee of stability in the viewed logs.
- Individual jobs can be rerun any number of times independent of other jobs in the same workflow. This means there isn't a "set" of related jobs that were executed at the same time, and this led me to remove the display of current status of jobs on the left-hand side of the view. There isn't a logical set of job statuses to display here.
Fixes#1043. Based upon @gmem's original work in #1416.

- the run ID used to download artifacts is absolute (ID) instead of being
relative to the repository (Index) for compatibility with the url built
and returned as `artifact-url` by the the upload-artifact@v4 action.
- this is a breaking change because URLs to download artifacts
previous saved/bookmarked and not yet expired expired are no
longer working, they need to be looked up again by visiting the job
web page.
- add unit tests for getRunByID().
- RepoActionView.test.js verifies the download URL is built using the
run ID.
- lAdd integration tests to verify the RunID is set as expected in
the template used by RepoActionView.vue.

- extract tests misplaced in
