feat: add DBA (Doing Business As) entity system for sellers

Implement complete DBA management allowing businesses to operate under multiple trade names with separate addresses, licenses, banking info, and invoice branding. Database: - Create business_dbas table with encrypted bank/tax fields - Add dba_id foreign key to crm_invoices Models: - BusinessDba model with encrypted casts, auto-slug, single-default enforcement - Business model: dbas(), activeDbas(), defaultDba(), getDbaForInvoice() - CrmInvoice model: dba() relationship, getSellerDisplayInfo() method Seller UI: - DbaController with full CRUD + set-default + toggle-active - Index/create/edit views using DaisyUI - Trade Names card added to settings index Admin: - DbasRelationManager for BusinessResource in Filament Migration: - MigrateDbaData command to convert existing dba_name fields
fix(ci): explicitly set DB_CONNECTION=pgsql in phpunit.xml
