Audit v2: fix security, data integrity, compliance, bugs, encoding, UX

Backend Security & Data Integrity: - Block negative debit/credit amounts that bypass balance validation - Require document date at posting (was optional, bypassing fiscal year checks) - Fix event sourcing anti-pattern: timestamps now stored in events, not UtcNow in Apply - Add [Authorize] to BankingController OAuth callback - Add company access check on attachment downloads - Validate CVR in CompanyAggregate.Create and CompanyAggregate.Update - Require company CVR for invoice creation (Momsloven §52) - Delete leftover WeatherForecastController - Fix duplicate migration number 007 (renamed to 007b) - Remove dead code in VatCalculationService (identical if/else branches) Accounting Compliance: - Add missing VAT accounts to StandardDanishAccounts (5610, 5611, 5620) - Populate SAF-T TaxInformation on transaction lines (was always null) - Add AuditFileCountry and TaxRegistrationNumber to SAF-T header Critical Frontend Bugs: - Fix Dashboard <a href> causing full page reloads (now uses React Router Link) - Wire Kassekladde filters to actual data (account, status, date range) - Pre-populate form when editing existing Kassekladde drafts - Add detail drawer for "Vis detaljer" action (was just a toast) - Toggle advanced filters with "Flere filtre" button - CloseFiscalYearWizard now actually posts closing entries via mutations - "Create next year" checkbox now creates the next fiscal year Danish Character Encoding (~50 fixes): - Fix ø/æ/å across Momsindberetning, DocumentUploadModal, Bankafstemning, Kontooversigt, CloseFiscalYearWizard, vatCodes, periodStore, periods, accounting, types/periods Dead Buttons & UX: - Disable Momsindberetning PDF/Export buttons with tooltips - FiscalYearSelector "Administrer" now navigates to Settings - Settings bank tab now uses real BankConnectionsTab component - Bankafstemning save button disabled with development tooltip - Replace hardcoded account options with real API data (Bankafstemning, Fakturaer) - Header help button shows info message, notification bell shows popover Consistency & Quality: - Remove 7 console.log statements from production code - Adopt PageHeader on 6 remaining pages (Kreditnotaer, Settings, Admin, etc.) - Standardize loading states to Skeleton pattern (5 pages) - Replace deprecated bodyStyle prop on Ant Design Cards - Standardize date format to DD-MM-YYYY - Fix sidebar width mismatch in designTokens - Fix Kontooversigt breadcrumb pointing to non-existent route Accessibility: - Add aria-label to sidebar navigation - Add +/- prefix to AmountText for color-blind users - Fix CompanySwitcher permanent skeleton when no companies Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
