Viktor Barzin 745e43c983 fix DB password desync + migrate remaining tfvars to Vault
DB desync fix: Stacks with Vault DB engine rotation (24h) now read
the password from vault-database ClusterSecretStore instead of vault-kv.
9 stacks updated with db ExternalSecrets reading from static-creds/*.

Stacks fixed: speedtest, hackmd, health, trading-bot, claude-memory,
woodpecker, linkwarden, nextcloud, url.

terraform.tfvars migration:
- plotting-book: google_client_id/secret → Vault KV + secret_key_ref
- tandoor: email_password var removed (was default="", now optional ESO)
- infra: ssh_private_key, vm_wizard_password, dockerhub_registry_password
  → Vault KV at secret/infra + data source
