fix(flux): move bedag HelmRepository to top-level to fix Flux race condition

The bedag HelmRepository was only declared inside flux/docs-site/, causing
a race condition where zip-enrichment, holidays, and air-quality HelmReleases
would fail with 'HelmRepository not found' if they reconciled before docs-site.

Move flux/docs-site/helmrepository.yaml -> flux/bedag-helmrepository.yaml and
add it as a top-level resource in flux/kustomization.yaml so it is always
available before any HelmRelease that depends on the bedag chart.

Closes leeworks-agents/api-company#87
