Take fider out of ArgoCD

[jacksonloper]

Draft on purpose. Do not merge until #73 and #52 are in.

Hands fider and fider-db to Flux by taking them out of the ApplicationSet. Removing the config.json files removes the Applications; removing the values.yaml files leaves nothing dead behind, since the Flux manifests in #52 carry their own copies.

Why this must wait for #73

Without preserveResourcesOnDeletion, merging this destroys the fider database:

Application fider-db  ->  owns postgresql.cnpg.io/Cluster/fider-db
Cluster fider-db      ->  ownerReference on PVC fider-db-1 (controller: true)
PVC fider-db-1        ->  PV pvc-df9a66c8, reclaim policy Delete

resources-finalizer deletes the Cluster, the garbage collector reaps the PVC, the PV reclaims. #73 turns that into an orphan instead.

Why it must wait for #52

#52 has to be on main before flux bootstrap can reconcile it. If this merges first, nothing manages fider at all — it keeps running, but drift and restarts stop being reconciled by anything.

Sequencing

Step	Change	Where
1	preserveResourcesOnDeletion: true	#73
2	Flux scaffold, suspended	#52
3	flux bootstrap	command
4	Helm-adoption stamping	commands
5	this PR	—
6	flux resume kustomization apps	command

Step 4 matters and is easy to skip: ArgoCD renders charts and applies manifests, so no Helm release exists in the cluster. Flux's helm-controller would try a fresh install of fider-db and collide. The objects need Helm ownership metadata stamped on them first — flux/README.md has the commands.

Step 6 stays separate so the two controllers never both manage these objects. Between 5 and 6 fider is unmanaged, which is fine and brief.

Not in scope

secrets/ is untouched. fider (JWT_SECRET, EMAIL_SMTP_PASSWORD) and fider-db-creds come from the standalone bootstrap-secrets app, which is not part of this ApplicationSet. Flux consumes those Secrets rather than managing them. Moving them to Flux SOPS needs Azure Key Vault workload identity for kustomize-controller and is a separate piece of work.

Rollback

Revert this PR. ArgoCD regenerates both Applications and re-adopts the resources. Suspend Flux first so they do not fight:

flux suspend kustomization apps
