- Created migration to add representation_cities table and domain, is_global fields to representations.
- Implemented SiteContextController to resolve domain to site context (city | representation | unknown).
- Developed DomainContext and DomainContextResolver services for domain mapping.
- Added tests for DomainContextResolver and commission logic based on domain ownership.
A representation editing its own record could raise its own commission or
self-activate (privilege escalation). Restrict both fields to ROLE_ADMIN and
range-check commission (0–100). Owner can still edit name/city/bank.
