Company search fixes

Resolved two issues affecting app users in company search:

• When filtering by technology category (e.g. "CRM Platforms") not showing a column per technology (e.g. "Salesforce", "Hubspot", "Zoho"...).
• When exporting a list of companies filtering by technology category, there was not a column for each technology of the category.
• When changing the technology filter, the table was filtering by the new technology, but a column was still showing the old technology.
