Mike Reeves 8225d41661 Harden postgres secrets, TLS enforcement, and admin tooling
- Deliver postgres super and app passwords via mounted 0600 secret files
  (POSTGRES_PASSWORD_FILE, SO_POSTGRES_PASS_FILE) instead of plaintext env
  vars visible in docker inspect output
- Mount a managed pg_hba.conf that only allows local trust and hostssl
  scram-sha-256 so TCP clients cannot negotiate cleartext sessions
- Restrict postgres.key to 0400 and ensure owner/group 939
- Set umask 0077 on so-postgres-backup output
- Validate host values in so-stats-show against [A-Za-z0-9._-] before SQL
  interpolation so a compromised minion cannot inject SQL via a tag value
- Coerce postgres:telegraf:retention_days to int before rendering into SQL
- Escape single quotes when rendering pillar values into postgresql.conf
- Own postgres tooling in /usr/sbin as root:root so a container escape
  cannot rewrite admin scripts
- Gate ES migration TLS verification on esVerifyCert (default false,
  matching the elastic module's existing pattern)
