The dashboard revenue windows (30/90/365 days) keyed purely on paid_at.
Imported historical invoices therefore landed in the recent window whenever
their paid_at sat there — notably legacy rows imported before commit c6b8cc9
began anchoring an import's paid_at to its issue_date, which still carry an
import-time paid_at. Recognise imported invoices (imported_pdf_path NOT NULL)
on their issue_date instead; native invoices keep cash-basis paid_at. No data
migration needed — fixes already-imported year-old invoices too.
