"""Pure-function tests for the default-enabled plugin set.

A fresh install (no stored plugin.* rows) should come up with the generic,
non-vendor-specific bundled plugins already enabled, while vendor-specific
plugins stay opt-in. An operator's stored choice must override the default.
No DB / Quart fixtures — we exercise to_plugins_cfg over the DEFAULTS dict
and a DEFAULTS-merged-with-stored dict, mirroring get_all_settings' merge.
