feat: point company search and contact match at real ClickHouse data

/companies/search queried a nonexistent 'companies' table; now queries
stg_apollo_organizations (5.26M organizations, typed/normalized layer).
/contacts/match queried a nonexistent 'contacts' table; now queries
apollo_persons_raw with LIKE matching, since emails/phone_numbers are
still raw list-repr text there -- exact matching needs a stg_apollo_persons
layer that doesn't exist yet.
