refactor(argocd): consolidate Applications (39→35)

Merge related Applications using multi-source pattern and PostSync hooks:

1. ingress-config ← wildcard-cert + homelab-ingress (2→1)
   - Both in k8s/bootstrap/ingress/, now use kustomization
   - Certificate deployed before Ingresses (wave 1)

2. homarr ← homarr + homarr-patches (2→1)
   - Added PostSync hook source (fix-probes-job.yaml)
   - Patches run after Helm chart deployment

3. temporal ← temporal + temporal-db-secret-sync (2→1)
   - Added PostSync hook source (copy-job.yaml)
   - DB secret sync runs after Temporal deployment

4. Removed duplicate: ingress-nginx Application
   - ingress-nginx-bootstrap (bootstrap) is working
   - Removed redundant ArgoCD-managed ingress-nginx
   - Eliminated duplicate DaemonSet

Skipped: cert-manager + cert-manager-issuers
  - Wave separation needed (CRDs before Issuers)
  - Keep separate for safety

Result: 39 → 35 Applications (-4, -10.3%)
