Mike Reeves 92a7bb3053 fix: get postsalt's PG-canonical pillar actually working end-to-end
Five blockers turned up the first time the so_pillar schema was applied
against a fresh standalone install. Fixing them in order:

1. 006_rls.sql ordering bug
   006 GRANTed on so_pillar.change_queue and its sequence, but the table
   isn't created until 008_change_notify.sql. 006 errored mid-file with
   "relation so_pillar.change_queue does not exist", short-circuiting the
   rest of the pillar staging chain. Moved the three change_queue grants
   into 008 alongside the table creation so each file is self-contained.

2. so_pillar_* roles unable to log in
   006 created the roles as NOLOGIN and set no password. Salt-master's
   ext_pillar (postgres) and the pg_notify_pillar engine both connect as
   so_pillar_master via TCP, so both came up with "password authentication
   failed for user so_pillar_master". Added a templated cmd.run step in
   schema_pillar.sls (so_pillar_role_login_passwords) that ALTERs all three
   roles WITH LOGIN PASSWORD pulling from secrets:pillar_master_pass — the
   same password ext_pillar_postgres.conf.jinja and the engines.conf
   pg_notify_pillar block render with.

3. Missing GRANT CONNECT ON DATABASE securityonion
   USAGE on the schema is granted in 006 but CONNECT on the database isn't.
   Engine + ext_pillar succeeded auth then died with "permission denied
   for database securityonion". Added the explicit GRANT CONNECT in 006.

4. psycopg2 missing from salt's bundled python
   /opt/saltstack/salt/bin/python3 doesn't ship psycopg by default, so
   when salt-master tries to load the pg_notify_pillar engine its
   `import psycopg2` fails inside salt's loader and the engine silently
   doesn't start (no error in the salt log — you only notice when nothing
   ever drains so_pillar.change_queue). Added a pip.installed state in
   schema_pillar.sls bound to that interpreter via bin_env.

5. engines.conf vs pg_notify_pillar_engine.conf list-replace
   Salt's master.d/*.conf merge replaces top-level lists rather than
   concatenating them. The engine config used to live in its own
   master.d/pg_notify_pillar_engine.conf with `engines: [pg_notify_pillar]`
   alongside the legacy `engines.conf` carrying `engines: [checkmine,
   pillarWatch]`. Whichever loaded last won, so the engine never showed
   up in the loaded set even when the file existed. Fold the
   pg_notify_pillar declaration into engines.conf (now jinja-rendered,
   gated on postgres:so_pillar:enabled), drop the standalone state from
   pg_notify_pillar_engine.sls, and delete the now-orphaned conf jinja.

End state validated against a live standalone-net install on the dev rig:
salt-master ext_pillar reads from so_pillar.* with no errors, the
pg_notify_pillar engine LISTENs on so_pillar_change and drains the
change_queue (134-row backlog → 0 within seconds), and a so-yaml replace
on a pillar key flows disk → PG → ext_pillar → salt pillar.get with the
new value visible after a saltutil.refresh_pillar.
