The site-settings loader kept an in-process map forever after a Redis miss
and promoted DEFAULTS (no logo/theme) to Redis on any DB error, so a build
that started before the DB was reachable stuck the site on the preset logo
and default theme until a manual reload or full restart.
- Redis miss now reloads from the database instead of the stale in-process map
- a DB failure returns defaults only as an in-process last resort and never
writes them to Redis, so the shared cache can't be poisoned by a transient
error at startup
- regression tests: DB re-read on Redis miss after cache expiry, defaults never
promoted to Redis, recovery from transient DB failure
