feat(backoffice): search customers by trade name and licence, filter by role

Staff search with whatever is in front of them. Company name, TIN, email
and profile reference already matched; a TIN's licence number and the
trade name of the business a role operates as did not, which is most of
what appears on a customer's own paperwork.

Adds a Role filter alongside it. Distinct from the existing Type pill:
that is the company's own kind, this asks "who does X?" — one `customer`
company routinely holds importer and exporter at once.

Both are EXISTS subqueries rather than constraints on the joined
`companyProfiles` alias. Filtering the join would drop the company's
other profiles from the loaded entity, so an importer-and-exporter would
render as importer-only.
