OdooSky v3 96071aec8e feat(chart): pg password via ExternalSecret/OpenBao (A-Chunk 1) ...

Per-instance Postgres password sourced from OpenBao via External
Secrets Operator. Dual-mode for the migration window:

  - postgres.passwordVaultPath unset → legacy postgres-secret.yaml
    renders with .Values.postgres.password (helm lookup + random
    fallback, bit-exact existing behaviour for live instances).
  - postgres.passwordVaultPath set → postgres-password-externalsecret.yaml
    renders an ExternalSecret that produces the same <release>-pg
    Secret (POSTGRES_USER/PASSWORD/DB) from OpenBao path
    `tenants/<tenant.id>/instances/<instance.code>/pg`.

Exactly one of the two templates ships per instance (mutually
exclusive `if`s on .Values.postgres.passwordVaultPath). The Postgres
StatefulSet envFroms <release>-pg unchanged.

OpenBao policy already grants the per-cluster ESO read on
`v3/data/tenants/<tenantID>/*` (buildEsoPolicy in tower's
openbao_auth_setup.go) — the new instances/<code>/pg subpath is
covered. No policy change required.

A `required` directive on the ExternalSecret asserts tenant.id is
present when passwordVaultPath is set — fails loud at helm template
time if Tower forgot to populate it.

deletionPolicy: Retain on the ExternalSecret. Postgres PGDATA on
disk hashes to the password in the Secret; an accidental ESO
removal must not cascade into the Secret disappearing.

Chart 0.1.6 → 0.1.7. Verified locally: helm template both modes,
helm lint clean.
