fix(billing): name ledger partners by company, not the NexaCloud user's full_name

One operator (e.g. "Gurpreet Singh") manages several distinct customer
businesses; naming partners from full_name mislabeled Mobility Specialties
Inc and Apex Vita Corporation as "Gurpreet Singh". Read the company field,
name the partner by company (mark is_company), and rewrite existing partners
so prior full_name-based names are corrected on re-ingest. 75 tests green.
