For a `pull_request_target` (PRT) run, Gitea loads the top-level
workflow from the trusted base branch, but any local reusable workflow
it calls (`uses: ./...`) was read from the PR **head** commit, which the
fork author controls.
## Fix
**Record the source commit where the content is read.**
`DetectedWorkflow` now carries a `SourceCommitSHA` filled in next to
`Content`, so the PRT detection pass at the base commit records the base
SHA automatically.
**Defense in depth.** `loadReusableWorkflowSource` pins the PR base
commit for a PRT run's local `uses: ./...` rather than trusting the
stored SHA. This also covers runs recorded before this change, whose
rows still hold the head SHA and would otherwise resolve from the fork
on rerun.
Existing run rows are not migrated.

Follow-up to https://github.com/go-gitea/gitea/pull/36564 (dynamic
matrix) and https://github.com/go-gitea/gitea/pull/36357 (max-parallel),
fixing issues found reviewing the two features together.
- **A placeholder could stall its run forever.** Its payload keeps the
raw matrix but loses its `needs`, so `ParseJob` re-expanded it instead
of reading it back — fatal for `include: ${{ fromJson(needs.*.outputs.*)
}}`.
- **An `if:` reading `matrix.*` skipped the whole job**, with or without
the `${{ }}`. It now reduces to the needs gate, except under
`always()`/`failure()`/`cancelled()`, and each combination is decided on
its own values once the matrix expands.
- **Dependents could be skipped before the combinations ran**, since
inserted siblings are absent from the resolver's job set. The pass now
stops after an insert and defers to the re-emit it schedules.
- **Expansion failures stranded the placeholder.** A retryable one is
returned so the queue retries it; a malformed payload fails the job
instead of requeueing forever.
- **Rerun could rewind a pass-through row** into a raw placeholder
keeping its old terminal status, which nothing expands. Now gated on the
anchor itself.
Plus: `max-parallel` distinguishes an unevaluated `${{ }}` (debug) from
a non-numeric literal (warn — it silently drops the cap).
