fix(bootstrap): complete Phase 4 ArgoCD bootstrap with all permanent fixes

- Fix ArgoCD Application schema: move syncOptions under syncPolicy (00-secrets.yaml)
- Remove helm install --wait flag (talos-cp-2 slow node timeout issue)
- Add comprehensive progress logging with timestamps to bootstrap.sh
- Fix SOPS key path (/Users/rockliang/.sops/key.txt, not homelab-age.key)
- Add local SOPS decryption for bootstrap secrets
- Add CNPG NetworkPolicy allowing app→database connectivity
- Disable Forgejo bundled dependencies (saves 66Gi storage)
- Inject database credentials via deployment.env (GITEA__DATABASE__*)
- Remove invalid ext4 mount options from StorageClass
- Add namespace manifests with PodSecurity labels
- Add encrypted forgejo-admin secret (SOPS)
- Reduce forgejo-db size 50Gi→25Gi per instance
- Prepare ArgoCD SOPS CMP plugin (for post-bootstrap)
