Full product audit: fix security, compliance, UX, and wire broken features

Security (Phase 1):
- Add authentication middleware on /graphql endpoint
- Filter company queries by user access (prevent IDOR)
- Add role-based authorization on mutations (owner/accountant)
- Reduce API key cache TTL from 24h to 5 minutes
- Hide exception details in production GraphQL errors
- Fix RBAC in frontend companyStore (was hardcoded)

Wiring broken features (Phase 2):
- Wire Kassekladde submit/void/copy to GraphQL mutations
- Wire Kontooversigt account creation to createAccount mutation
- Wire Settings save to updateCompany mutation
- Wire CreateFiscalYearModal and CloseFiscalYearWizard to mutations
- Replace Momsindberetning mock data with real useVatReport query
- Remove Dashboard hardcoded percentages and fake VAT deadline
- Fix Kreditnotaer invoice selector to use real data
- Fix mutation retry from 1 to 0 (prevent duplicate operations)

Accounting compliance (Phase 3):
- Add balanced entry validation (debit==credit) in JournalEntryDraftAggregate
- Add fiscal year boundary enforcement (status, date range checks)
- Add PostedAt timestamp to posted events (Bogføringsloven §7)
- Add account number uniqueness check within company
- Add fiscal year overlap and gap checks
- Add sequential invoice auto-numbering
- Fix InvoiceLine VAT rate to use canonical VatCodes
- Fix SAF-T account type mapping (financial → Expense)
- Add DraftLine validation (cannot have both debit and credit > 0)

UX improvements (Phase 4):
- Fix Danish character encoding across 15+ files (ø, æ, å)
- Deploy DemoDataDisclaimer on pages with mock/incomplete data
- Adopt PageHeader component universally across all pages
- Standardize active/inactive filtering to Switch pattern
- Fix dead buttons in Header (Help, Notifications)
- Remove hardcoded mock data from Settings
- Fix Sidebar controlled state and Kontooversigt navigation
