feat(reports): PDF download for Resultatrapport and Balansrapport (#366)

* feat(reports): PDF download for Resultatrapport and Balansrapport User feedback after merging #363: "Ladda ner PDF saknas för de nya resultat- och balansrapporterna." The previous PR deferred PDFs to a follow-up; this is the follow-up. New operational PDF template (`operational-report-pdf-template.tsx`) with two exports — ResultatrapportPDF and BalansrapportPDF. Mirrors the visual style of the formal FinancialStatementPDF but **omits the yellow "Arbetsutkast – ej undertecknat" disclaimer**, which only belongs on draft årsredovisning per ÅRL 2:7 §. These are löpande reports, never an årsredovisning at any stage. Resultatrapport PDF: account / name / current period / prior period (prior column hidden when no previous fiscal period exists), grouped by BAS account class with subtotals and a "Beräknat resultat" summary line. Balansrapport PDF: account / name / IB / UB / förändring per class 1 and class 2, with the same Balanscheck card the on-screen view shows (Summa tillgångar, Summa eget kapital + reserver + skulder, Beräknat resultat ej bokslutsjusterat, Balanserar / Balanserar ej verdict). Wired up "Ladda ner PDF" buttons on both ResultatrapportView and BalansrapportView. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(reports): prevent PDF row truncation; align Balansrapport filename Two crucial fixes from the PR review: - Drop wrap={false} from the outer group <View> in both PDFs. With wrap=false on a group exceeding one A4 page, @react-pdf/renderer silently clips overflow rows. Large class 1 (80+ active accounts on a real company) was at risk of dropping rows from the rendered file with no warning. Outer group now wraps; wrap={false} retained on individual rows and the subtotal so neither breaks mid-line. - Balansrapport filename anchor changed from period.end to period.start to match the convention used by resultatrapport, balance-sheet, and income-statement PDF routes. The Swedish compliance bot preferred period.end (snapshot semantics), Greptile preferred period.start (cross-route consistency); the latter wins because predictable sorting/renaming matters for archived räkenskapsinformation.
