feat: UI slop cleanup, invoice icon/header polish + year-end in Rapporter, journal-list DataList refactor (#847)

UI cleanup: removed AI-slop (redundant suppliers subtitle, decorative Sparkles glyph), decluttered the article-detail header (single status badge + muted type · #number), standardized the invoice icon Receipt→ReceiptText (no $ in a SEK app), and matched ReportExportMenu trigger size to the primary CTA on list pages.

Bookkeeping: surfaced year-end closing in Rapporter (catalog descriptor) and dropped the redundant header button; refactored JournalEntryList to DataList primitives + chunked /api/documents/counts in 50-ID batches (large pages previously 400'd); added optional fraction-digit overrides to formatCurrency. The fiscal-year lock indicator is preserved as a labeled Låst/Stängt badge in FiscalYearSelector.

All PR-bot findings triaged as false positives (unused import, formatCurrency öre, lock indicator) or intentional design (year-end placement, empty-state messaging). CI green.
