fix(ci): run Renovate via official Docker image (#12)
## Summary
First Renovate run failed with `reference not found` on `renovatebot/github-action@v40` — act_runner's go-git clone couldn't resolve the major-rolling tag (whether the upstream tag is missing or it's a go-git tag-fetch quirk doesn't really matter — the wrapper action is the wrong layer to fight).

Switch to invoking the official `renovate/renovate:40` Docker image directly. The job container already has the host Docker socket mounted (per `ci-runners.compose.yml`), so the sibling `docker run` works out of the box. Renovate clones the target repo itself via API + token, so no `actions/checkout` or bind-mount is needed.

Net result:
- Decoupled from third-party action-tag resolution.
- Renovate runtime version explicitly pinned (reproducible).
- One fewer indirection to debug.

## Test plan
- [ ] After merge, trigger the workflow manually (Actions → Renovate → Run workflow).
- [ ] Job pulls `renovate/renovate:40` (~1 GB, one-time on this runner host) and runs without "reference not found".
- [ ] Renovate creates the onboarding PR ("Configure Renovate") visible in the repo's PR list, signed by `apf-portal-bot`.

# Per ADR-0015 (CI/CD on Gitea Actions). Scheduled invocation of
# Renovate Bot, which proposes dependency updates as PRs against main.
#
# Configuration of the *bot's behaviour* (groupings, schedules, labels,
# auto-merge, vulnerability sources) lives in /renovate.json at the
# repo root. This workflow only controls *when* Renovate runs and how
# it authenticates against Gitea.
#
# Implementation note — we run the official `renovate/renovate` Docker
# image directly via `docker run` rather than the `renovatebot/github-
# action` wrapper. The wrapper relies on act_runner being able to
# resolve arbitrary GitHub tags via go-git, which is brittle (we hit
# `reference not found` on `@v40`). Going straight to the image:
# * decouples from action-tag resolution issues;
# * pins the Renovate runtime version explicitly (reproducible);
# * one fewer layer of indirection to debug.
#
# Renovate clones the repo itself using RENOVATE_TOKEN — no
# `actions/checkout` step, no host bind-mount needed.
#
# Authentication: a Gitea Personal Access Token issued for the dedicated
# `apf-portal-bot` user, stored as the RENOVATE_TOKEN secret. The full
# bot-onboarding procedure lives in docs/development.md → "Dependency
# updates (Renovate)".
