chore(deps): update pre-commit hook gitlab-com/gl-infra/common-ci-tasks to v4.15

See merge request !1606

chore(deps): update alpine docker tag to v3.24

See merge request !1548

Drop the user-facing fairway_manifest input and derive it as
<runway_dir>/fairway.yaml. This consolidates Fairway and Runway v2
configuration under a single directory, matching the convention
proposed in the MR discussion.

- Remove the v1 runwayctl helm-chart include (release-platform
  consumers should use the Fairway-driven v2 path only).
- Gate the v2 service include on runway_service_id + runway_dir.
- Gate the Fairway helm-chart include on runway_dir.
- Forward <runway_dir>/fairway.yaml to both components.
- Drop the empty-fairway_manifest check in generate-publish-pipeline;
  the file-existence check below already catches misconfigurations.

Refs: !1572

Keep the fairway_manifest input on the schema so existing consumers do
not break on the upgrade, but mark it deprecated. The value is ignored;
the manifest path is now derived from runway_dir.
