chore(argocd): sync Application manifests with live cluster state

- Update the 5 Applications that still pointed at the internal Gitea URL
  (gitea.gitea.svc.cluster.local) to https://git.chemavx.xyz, matching the
  live patch that made the Gitea->ArgoCD webhook effective for them.
- Add the 9 Applications that existed only in the cluster (filebrowser,
  ghost-en, k8s-manifests, ollama, renovate, researchowl, trilium, umami,
  zona-exclusion) so a cluster rebuild can restore all 14 from git.

Files are verbatim dumps of the live spec. Note: the old
application-polymarket-bot.yaml and application-n8n.yaml in git carried
telegram notification annotations and prune:true that were NOT live; this
snapshot replaces them with what actually runs.
