-- Wires up the normalized `manufacturers` catalog (organized-ideas.md §3:
-- "manufacturer becomes a normalized, submittable catalog — the same
-- public/user-defined pattern already used for device categories").
--
-- The table itself, its RLS policies, and device_templates.manufacturer_id
-- have all existed unused since the initial schema / the manufacturer_text
-- migration — this is the pass that actually populates and reads them.
-- Scope matches what device_category has today: create-your-own-private-one
-- only, no submission/admin-edit UI yet (that's a separate, already-tracked
-- follow-up for both entities together).
--
-- Any existing free-text manufacturer values (there's realistically at most
-- a handful of dev-only rows at this point, nothing shipped) get backfilled
-- into a manufacturers row each, grouped by (name, owner, is_public) so two
-- different users' private "Fake" manufacturers don't collide into one row.
