make so-yaml PG-canonical and add pillar-change reactor stack

Two coupled changes that together let so_pillar.* be the canonical
config store, with config edits driving service reloads automatically:

so-yaml PG-canonical mode
- Adds /opt/so/conf/so-yaml/mode (and SO_YAML_BACKEND env override) with
  three values: dual (legacy), postgres (PG-only for managed paths),
  disk (emergency rollback). Bootstrap files (secrets.sls, ca/init.sls,
  *.nodes.sls, top.sls, ...) stay disk-only regardless via the existing
  SkipPath allowlist in so_yaml_postgres.locate.
- loadYaml/writeYaml/purgeFile now route to so_pillar.* in postgres
  mode: replace/add/get all read+write the database with no disk file
  ever appearing. PG failure is fatal in postgres mode (no silent
  fallback); dual mode preserves the prior best-effort mirror.
- so_yaml_postgres gains read_yaml(path), is_pg_managed(path), and
  is_enabled() so so-yaml can answer "is this path PG-managed and is
  PG up" without reaching into private helpers.
- schema_pillar.sls writes /opt/so/conf/so-yaml/mode = postgres after
  the importer succeeds, so flipping postgres:so_pillar:enabled flips
  so-yaml's behavior in lockstep with the schema being live.

pg_notify-driven change fan-out
- 008_change_notify.sql adds so_pillar.change_queue + an AFTER trigger
  on pillar_entry that enqueues the locator and pg_notifies
  'so_pillar_change'. Queue is drained at-least-once so engine restarts
  don't lose events; pg_notify is just the wakeup signal.
- New salt-master engine pg_notify_pillar.py LISTENs on the channel,
  drains the queue with FOR UPDATE SKIP LOCKED, debounces bursts, and
  fires 'so/pillar/changed' events grouped by (scope, role, minion).
- Reactor so_pillar_changed.sls catches the tag and dispatches to
  orch.so_pillar_reload, which carries a DISPATCH map of pillar-path
  prefix -> (state sls, role grain set) so adding a new service to
  the auto-reload list is a one-line edit instead of a new reactor.
- Engine + reactor wiring is gated on the same postgres:so_pillar:enabled
  flag as the schema and ext_pillar config so the whole stack flips
  on/off together.

Tests: 21 new cases (112 total, all passing) covering mode resolution,
PG-managed detection, and PG-canonical read/write/purge routing with
the PG client stubbed.

+so_yaml_postgres — Postgres-backed dual-write helpers for so-yaml.py.
+
+so-yaml.py writes YAML pillar files on disk; this module mirrors those
+writes into so_pillar.* in so-postgres so ext_pillar and the SOC
+PostgresConfigstore see the same data. During the postsalt transition
+disk is canonical; PG writes are best-effort and never fail the disk
+operation.
+
+Connection: shells out to `docker exec so-postgres psql -U postgres -d
+securityonion`. Same pattern so-pillar-import uses; avoids needing a
+separate DSN config at install time. Performance is fine because so-yaml
+is invoked from infrequent code paths (setup scripts, so-minion,
+so-firewall); SOC's hot path uses the in-process pgxpool in
+PostgresConfigstore, not so-yaml.
+
+Path-to-row mapping mirrors PostgresConfigstore.locateSetting in
+securityonion-soc:
+
+  /opt/so/saltstack/local/pillar/<section>/soc_<section>.sls
+        -> scope=global, pillar_path=<section>.soc_<section>
+  /opt/so/saltstack/local/pillar/<section>/adv_<section>.sls
+        -> scope=global, pillar_path=<section>.adv_<section>
+  /opt/so/saltstack/local/pillar/minions/<id>.sls
+        -> scope=minion, minion_id=<id>, pillar_path=minions.<id>
+  /opt/so/saltstack/local/pillar/minions/adv_<id>.sls
+        -> scope=minion, minion_id=<id>, pillar_path=minions.adv_<id>
+
+Files outside that mapping (notably secrets.sls, postgres/auth.sls,
+elasticsearch/nodes.sls, etc.) are skipped — they stay disk-only forever
+or render dynamically and don't belong in PG.

+
+Why a queue + notify rather than just notify: pg_notify is fire-and-forget
+within a session. If the engine is down or the LISTEN connection is broken
+when a write happens, the notification is lost forever. The change_queue
+lets us recover — on (re)connect, we drain everything still flagged
+processed_at IS NULL.
+
+Debounce: bulk operations (so-pillar-import, fresh installs) can fire
+hundreds of notifications per second. The engine collects whatever lands in
+a short window and emits one event per (scope, role, minion) tuple so the
+reactor isn't stampeded.
