feat(migrations): add supplier invoice enhancements for accounting integration

- Added new columns to supplier_invoice_lines for contra_account, line_purpose, resale_customer_id, resale_order_number, is_invoiced_to_customer, and invoiced_date.
- Created indexes for faster filtering by purpose and resale status.
- Introduced economic_accounts table to cache e-conomic chart of accounts with relevant fields and indexes.
- Added comments for documentation on new columns and tables.
- Included success message for migration completion.

+# Migration Guide - Supplier Invoice Enhancements (v2.0.0)
+
+## 🎯 Hvad migreres:
+
+### Database Changes:
+- ✅ `supplier_invoice_lines`: Nye kolonner (contra_account, line_purpose, resale_customer_id, resale_order_number)
+- ✅ `economic_accounts`: Ny tabel til e-conomic kontoplan cache
+
+### Backend Changes:
+- ✅ e-conomic accounts API integration
+- ✅ Line item update endpoint med modkonto support
+
+### Frontend Changes:
+- ✅ 3 nye faneblade (Til Betaling, Klar til Bogføring, Varelinjer)
+- ✅ Inline redigering af modkonto og formål
+- ✅ Backup version på /billing/supplier-invoices2
+
+---
+
+## 📋 Pre-Migration Checklist:
+
+- [ ] Commit alle ændringer til git
+- [ ] Test på lokal udvikling fungerer
+- [ ] Backup af production database
+- [ ] Tag ny version (v2.0.0)
+- [ ] Push til Gitea
+
+---
+
+## 🚀 Migration Steps:
+
+### Step 1: Commit og Tag Release
+
+```bash
+cd /Users/christianthomas/DEV/bmc_hub_dev
+
+# Commit ændringer
+git add .
+git commit -m "Supplier invoice enhancements v2.0.0
+
+- Added modkonto (contra_account) support per line
+- Added line_purpose tracking (resale, internal, project, stock)
+- Added e-conomic accounts API integration
+- Redesigned frontend with 3 tabs: Payment, Ready for Booking, Line Items
+- Database migration 1000 included
+- Backup version available at /billing/supplier-invoices2"
+
+# Opdater VERSION fil
+echo "2.0.0" > VERSION
+
+git add VERSION
+git commit -m "Bump version to 2.0.0"
+
+# Tag release
+git tag v2.0.0
+git push origin main
+git push origin v2.0.0
+```
+
+### Step 2: Backup Production Database
+
+```bash
+# SSH til production
+ssh bmcadmin@172.16.31.183
+
+# Backup database
+cd /srv/podman/bmc_hub_v1.0
+podman exec bmc-hub-postgres-prod pg_dump -U bmc_hub bmc_hub > backup_pre_v2.0.0_$(date +%Y%m%d_%H%M%S).sql
+
+# Verificer backup
+ls -lh backup_pre_v2.0.0_*.sql
+```
+
+### Step 3: Deploy ny Version
+
+Fra lokal Mac:
+
+```bash
+cd /Users/christianthomas/DEV/bmc_hub_dev
+
+# Kør deployment script
+./deploy_to_prod.sh v2.0.0
+```
+
+Dette script:
+1. Opdaterer RELEASE_VERSION i .env
+2. Stopper containers
+3. Bygger nyt image fra Gitea tag v2.0.0
+4. Starter containers igen
+
+### Step 4: Kør Migration på Production
+
+```bash
+# SSH til production
+ssh bmcadmin@172.16.31.183
+cd /srv/podman/bmc_hub_v1.0
+
+# Kør migration SQL
+podman exec -i bmc-hub-postgres-prod psql -U bmc_hub -d bmc_hub < migrations/1000_supplier_invoice_enhancements.sql
+
+# ELLER hvis migrationen ikke er mounted:
+# Kopier migration til container først:
+podman cp migrations/1000_supplier_invoice_enhancements.sql bmc-hub-postgres-prod:/tmp/migration.sql
+podman exec bmc-hub-postgres-prod psql -U bmc_hub -d bmc_hub -f /tmp/migration.sql
+```
+
+### Step 5: Sync e-conomic Accounts
+
+```bash
+# Trigger initial sync af kontoplan
+curl -X GET "http://172.16.31.183:8001/api/v1/supplier-invoices/economic/accounts?refresh=true"
+
+# Verificer at konti er cached
+curl -s "http://172.16.31.183:8001/api/v1/supplier-invoices/economic/accounts" | jq '.accounts | length'
+# Skal returnere antal konti (fx 20)
+```
+
+### Step 6: Verificer Migration
+
+```bash
+# Tjek database kolonner
+podman exec bmc-hub-postgres-prod psql -U bmc_hub -d bmc_hub -c "\d supplier_invoice_lines"
+# Skal vise: contra_account, line_purpose, resale_customer_id, resale_order_number
+
+# Tjek economic_accounts tabel
+podman exec bmc-hub-postgres-prod psql -U bmc_hub -d bmc_hub -c "SELECT COUNT(*) FROM economic_accounts;"
+# Skal returnere antal accounts (fx 20)
+
+# Test frontend
+# Åbn: http://172.16.31.183:8001/billing/supplier-invoices
+# Skal vise: Til Betaling, Klar til Bogføring, Varelinjer tabs
+
+# Test backup version
+# Åbn: http://172.16.31.183:8001/billing/supplier-invoices2
+# Skal vise: Original version med Fakturaer, Mangler Behandling tabs
+```
+
+---
+
+## 🔄 Rollback Plan (hvis noget går galt):
+
+### Option 1: Rollback til forrige version
+
+```bash
+ssh bmcadmin@172.16.31.183
+cd /srv/podman/bmc_hub_v1.0
+
+# Opdater til forrige version (fx v1.3.123)
+sed -i 's/^RELEASE_VERSION=.*/RELEASE_VERSION=v1.3.123/' .env
+
+# Rebuild og restart
+podman-compose down
+podman-compose build --no-cache
+podman-compose up -d
+```
+
+### Option 2: Restore database backup
+
+```bash
+ssh bmcadmin@172.16.31.183
+cd /srv/podman/bmc_hub_v1.0
+
+# Stop API for at undgå data ændringer
+podman stop bmc-hub-api-prod
+
+# Restore database
+podman exec -i bmc-hub-postgres-prod psql -U bmc_hub -d bmc_hub < backup_pre_v2.0.0_XXXXXXXX.sql
+
+# Restart API
+podman start bmc-hub-api-prod
+```
+
+---
+
+## 📊 Post-Migration Validation:
+
+### Test Cases:
+
+1. **Upload Invoice**
+   - Upload PDF faktura
+   - Verificer Quick Analysis virker
+   - Tjek vendor auto-match
+
+2. **Process Invoice**
+   - Klik "Behandl" på uploaded fil
+   - Verificer template extraction
+   - Tjek at linjer oprettes
+
+3. **Assign Modkonto**
+   - Gå til "Varelinjer" tab
+   - Vælg modkonto fra dropdown (skal vise 20 konti)
+   - Vælg formål (Videresalg, Internt, osv.)
+   - Gem og verificer
+
+4. **Check Ready for Booking**
+   - Gå til "Klar til Bogføring" tab
+   - Skal kun vise fakturaer hvor ALLE linjer har modkonto
+   - Test "Send til e-conomic" knap
+
+5. **Payment View**
+   - Gå til "Til Betaling" tab
+   - Verificer sortering efter forfaldsdato
+   - Test bulk selection
+
+---
+
+## 🎯 Success Criteria:
+
+- ✅ Migration SQL kørt uden fejl
+- ✅ 20+ e-conomic accounts cached i database
+- ✅ Nye faneblade vises korrekt
+- ✅ Modkonto dropdown virker
+- ✅ Inline editing af linjer fungerer
+- ✅ Backup version tilgængelig på /supplier-invoices2
+- ✅ Send til e-conomic virker med nye modkonti
+
+---
+
+## ⚠️ Known Issues & Workarounds:
+
+### Issue 1: Accounts endpoint timeout
+**Symptom**: Første kald til accounts endpoint er langsomt (2-3 sek)
+**Reason**: Første gang syncer fra e-conomic API
+**Workaround**: Pre-trigger sync efter deployment (Step 5)
+
+### Issue 2: Eksisterende fakturaer har ingen modkonto
+**Symptom**: Gamle fakturaer vises ikke i "Klar til Bogføring"
+**Expected**: Kun nye fakturaer (efter migration) vil have modkonti
+**Solution**: Manuel assignment via "Varelinjer" tab for gamle fakturaer hvis nødvendigt
+
+### Issue 3: Browser cache
+**Symptom**: Gamle faneblade vises stadig
+**Solution**: Ctrl+Shift+R (hard refresh) i browser
+

+
+## 📞 Support:
+
+Ved problemer, tjek:
+1. Container logs: `podman logs bmc-hub-api-prod --tail 100`
+2. Database logs: `podman logs bmc-hub-postgres-prod --tail 100`
+3. Migration status: `podman exec bmc-hub-postgres-prod psql -U bmc_hub -d bmc_hub -c "SELECT * FROM economic_accounts LIMIT 5;"`
