feat(etrade): take the selected licence's trade name as the company name

A TIN routinely trades under a name that is not its registered one, and
holds several licences with different trade names — of 58 TINs checked
against eTrade, 8 had at least one licence whose trade name differs from
the registered `BusinessName`, one of them across three licences.

`extractRegistrationData` now resolves `companyName` from the selected
licence's `TradeName`, falling back to `BusinessName` (16 of 309 licences
carry a blank trade name, so the fallback is load-bearing).

EIMS is pinned back to `BusinessName` for the seller's `LegalName`: an
invoice is a MoR tax filing and must carry the legal entity, not the
trade name. It is the only other caller.
