feat(manufacturing): enrich inventory list with customer/user details and filters

The inventory list and detail page previously only showed raw
customer_id / user_list references. list_devices now batch-resolves
customer names and user display names/emails (via Firestore get_all(),
avoiding an N+1 round trip per device) and exposes them as
customer_name / users on DeviceInventoryItem. Search now matches
against device name, console name, customer name, and assigned users
in addition to serial/owner/batch.

Also adds hw_types (multi-select board type) and has_users filters to
GET /manufacturing/devices, and carries console_name through for
display. DeviceInventoryDetail is updated to show and use all of this
(customer name, assigned users, new UI components for signal/charts).
