getCache()

• SQLEntity.getCache(). Boot-time / cache-warmup helper that selects every
  active row (archived IS FALSE, no LIMIT, ordered by id ASC) and returns
  [] when nothing matches. Extra caller filters are merged on top; a
  caller-supplied archived filter is overwritten so soft-deleted rows cannot
  enter the cache. Requires a filterable archived property on the entity.
  Unlike get(), an empty table is not treated as a 404.
