Extends POST /api/admin/lidarr/test response to include quality_profiles,
metadata_profiles, root_folders, and an optional list_errors map when the
Lidarr connection succeeds. The three list fetches run in parallel after
the ping; any per-list failure goes into list_errors so the response can
still report ok=true with whatever data did come back. Failed-ping
response shape is unchanged.
This lets /admin/integrations populate its dropdowns on a single
round-trip during first-time setup, fixing the chicken-and-egg where
the dropdowns previously gated on cfg.Enabled (which can't be true
until the first save, which itself needs non-zero defaults).
