feat: Enhance billing frontend with Jinja2 templates and improve invoice handling

- Updated billing frontend views to use Jinja2 templates for rendering HTML pages.
- Added support for displaying supplier invoices, template builder, and templates list with titles.
- Introduced a new configuration setting for company CVR number.
- Enhanced OllamaService to support credit notes in invoice extraction, including detailed JSON output format.
- Improved PDF text extraction using pdfplumber for better layout handling.
- Added a modal for editing vendor details with comprehensive fields and validation.
- Implemented invoice loading and display functionality in vendor detail view.
- Updated vendor management to remove priority handling and improve error messaging.
- Added tests for AI analyze endpoint and CVR filtering to ensure correct behavior.
- Created migration script to support credit notes in the database schema.

 VIGTIGE REGLER:
 1. Returner KUN gyldig JSON - ingen forklaring eller ekstra tekst
 2. Hvis et felt ikke findes, sæt det til null
 3. Beregn confidence baseret på hvor sikker du er på hvert felt (0.0-1.0)
 4. Datoer skal være i format YYYY-MM-DD
-5. Tal skal være decimaler (brug . som decimalseparator)
+5. DANSKE PRISFORMATER: 
+   - Tusind-separator kan være . (punkt) eller mellemrum: "5.965,18" eller "5 965,18"
+   - Decimal-separator er , (komma): "1.234,56 kr"
+   - I JSON output skal du bruge . (punkt) som decimal: 1234.56
+   - Eksempel: "5.965,18 kr" → 5965.18 i JSON
+   - Eksempel: "1.234,56 DKK" → 1234.56 i JSON
 6. CVR-nummer skal være 8 cifre uden mellemrum
 7. Moms/VAT skal udtrækkes fra hver linje hvis muligt
+8. DOKUMENTTYPE DETEKTION:
+   - "invoice" = Almindelig faktura
+   - "credit_note" = Kreditnota (refusion, tilbagebetaling, korrektion)
+   - Kig efter ord som: "Kreditnota", "Credit Note", "Refusion", "Tilbagebetaling", "Godtgørelse"
+9. BELØB OG FORTEGN (ABSOLUT KRITISK):
+   - **ALMINDELIGE FAKTURAER**: Alle beløb skal være POSITIVE tal (total_amount > 0, line_total > 0)
+   - **KREDITNOTAER**: Alle beløb skal være NEGATIVE tal (total_amount < 0, line_total < 0)
+   - Hvis dokumentet siger "Faktura" → document_type: "invoice" → POSITIVE beløb
