chore: enroll in Renovate

This project has received no dependency updates since it was created on 2026-06-11, despite carrying app/pyproject.toml, app/requirements.txt and two Dockerfiles. It has no Dependency Dashboard and no renovate/* branch.

Renovate's own log gives the reason:

INFO: Repository is a fork and not manually configured - skipping
      - did you want to run with --fork-processing=enabled?

Renovate skips forks unless the repository is "manually configured", meaning it carries its own renovate.json. The estate enrolls projects by injecting the shared preset as base config (RENOVATE_REQUIRE_CONFIG: optional), and that inherited enrollment does not satisfy the fork test. So a fork is enrolled in name only, and silently: no dashboard, no branches, no error anywhere to notice.

This file makes the project manually configured. It adds no overrides, only naming the shared preset, so behaviour matches every other consumer in the group.

Two of 57 repositories were being skipped this way. The other, lab/version-gitlab-com-simulation, is a lab and carries no renovation obligation.

Found by the new renovate-fleet-audit job in the catalog (pipeline!124 (merged)), which reads every enrolled project's dashboard after each Renovate run. The audit is being extended to assert this class directly, since fork status and the absence of a local config are both readable from the project API without needing the log.
