What's new

Features

• Client detail page now shows payment history grouped by period (Accrued, Paid, Cancelled, Pending) instead of a flat list of individual entries
• Calculations page period summary now includes Cancelled amount so totals always balance: Accrued = Paid + Cancelled + Pending

• Automated database auditing — all data mutations are now tracked with user and session context via PostgreSQL triggers

Bug Fixes

• Fixed tariff creation when no active tariff exists for a service
• Fixed 301 redirect loop on page reload (F5) when using Next.js static export

Upgrade notes

Run make migrate-up to apply the new audit trigger migration before starting the server.
