paperless-ngx: migrate to proxmox-lvm-encrypted

Browse source 
Document scans (receipts, contracts, IDs) are unambiguously sensitive
PII. Storage decision rule defaults sensitive data to
`proxmox-lvm-encrypted`, but paperless-ngx had been left on plain
`proxmox-lvm` by an abandoned migration attempt that left a dormant,
non-Terraform-managed encrypted PVC sitting unbound for 11 days.

Cleaned up the orphan, added the encrypted PVC properly via Terraform,
rsynced data with deployment scaled to 0, swapped claim_name. Plain
`proxmox-lvm` PVC retained for a 7-day soak before removal.

5. **Passphrase management**: ExternalSecret syncs passphrase from Vault KV (`secret/viktor/proxmox_csi_encryption_passphrase`) → K8s Secret. Backup key at `/root/.luks-backup-key` on PVE host.
**Services on encrypted storage (2026-04-15 migration):**
vaultwarden, dbaas (mysql+pg+pgadmin), mailserver, nextcloud, forgejo, matrix, n8n, affine, health, hackmd, redis, headscale, frigate, meshcentral, technitium, actualbudget, grampsweb, owntracks, paperless-ngx, wealthfolio, monitoring (alertmanager)

**Services migrated later** (post-audit catch-up): paperless-ngx (2026-04-25 — sensitive document scans had been left on plain `proxmox-lvm` by an abandoned attempt; rsync swap cleaned up the orphan and re-did via Terraform).
**CSI node plugin memory**: Requires 1280Mi limit for LUKS2 Argon2id key derivation (~1GiB). Set via `node.plugin.resources` in Helm values (not `node.resources`).
