feat: Implement email management UI with FastAPI and keyword-based classification

- Added FastAPI router for serving email management UI at /emails
- Created Jinja2 template for the email frontend
- Developed SimpleEmailClassifier for keyword-based email classification
- Documented email UI implementation details, features, and API integration in EMAIL_UI_IMPLEMENTATION.md

-1. **invoice** - Fakturaer fra leverandører (inkl. kreditnotaer)
-2. **freight_note** - Fragtbreve og forsendelsesbekræftelser
-3. **order_confirmation** - Ordrebekræftelser fra leverandører
-4. **time_confirmation** - Bekræftelser på tidsforbrug/timer (fra kunder eller interne)
-5. **case_notification** - Notifikationer om sager, support tickets, opgaver
-6. **customer_email** - Generelle kundehenvendelser (spørgsmål, feedback, klager)
-7. **bankruptcy** - Konkursmeldinger, rekonstruktion, betalingsstandsning
-8. **general** - Almindelig kommunikation (opdateringer, møder, newsletters)
-9. **spam** - Spam, reklame, phishing
-10. **unknown** - Kan ikke klassificeres med sikkerhed
+Rules:
+- invoice: Contains invoice number, amount, or payment info
+- time_confirmation: Time/hours confirmation, often with case references
+- case_notification: Notifications about specific cases (CC0001, Case #123)
+- bankruptcy: Explicit bankruptcy/insolvency notice
+- Be conservative: Use general or unknown if uncertain
 
-**Vigtige regler:**
-- `invoice` skal indeholde fakturanummer, beløb, eller betalingsinformation
-- `time_confirmation` indeholder timer/tidsforbrug, ofte med case/sagsreferencer
-- `case_notification` er notifikationer om specifikke sager (CC0001, Case #123 osv.)
-- `bankruptcy` kun hvis der er EKSPLICIT konkursmelding

+   - `e` - Archive
+   - `r` - Reprocess
+   - `c` - Focus classification dropdown
+   - `x` - Toggle selection
+   - `/` or `Cmd+K` - Focus search
+   - `Esc` - Clear selection
+   - `?` - Show shortcuts help modal
+
+7. **Modals**
+   - Email Rules modal (list/create/edit/delete rules)
+   - Keyboard shortcuts help modal
+
+### ✅ Backend Integration
+
+- **API Endpoints**: All 11 email endpoints from `app/emails/backend/router.py`
+- **Frontend Route**: `/emails` serves `app/emails/frontend/emails.html`
+- **Navigation**: Added "Email" link to top navbar
+- **Auto-refresh**: Polls every 30 seconds for new emails
+
+### ✅ Design System Compliance
+
+- **Nordic Top Colors**: Deep blue `#0f4c75` accent, clean white cards
+- **Dark Mode**: Full support with CSS variable theme switching
+- **Bootstrap 5**: Grid, buttons, badges, modals, tooltips
+- **Bootstrap Icons**: Consistent iconography throughout
+- **Responsive**: Mobile-friendly with collapsing columns (<768px hides analysis sidebar)
+
+### ✅ Classification Badges
+
+Color-coded pills for email types:
+- 📄 **Invoice**: Green (#d4edda)
+- 📦 **Order Confirmation**: Blue (#d1ecf1)
+- 🚚 **Freight Note**: Yellow (#fff3cd)
+- ⏰ **Time Confirmation**: Gray (#e2e3e5)
+- 📋 **Case Notification**: Light blue (#cce5ff)
+- ⚠️ **Bankruptcy**: Red (#f8d7da)
+- 🚫 **Spam**: Dark (#343a40)
+- 📧 **General**: Light gray (#e9ecef)
+
+## Usage
+
+1. **Navigate to**: http://localhost:8001/emails
+2. **Browse emails** in left sidebar (30 emails loaded by default)
+3. **Click email** to view content in center pane
+4. **Edit classification** in right sidebar AI analysis panel
+5. **Use keyboard shortcuts** for power-user workflow
+6. **Bulk select** with checkboxes for batch operations
+7. **Search** with debounced search bar
+8. **Filter** by classification with pill buttons
+
+## Technical Details
+
+### Files Created/Modified
+
+1. **`app/emails/frontend/emails.html`** (1100+ lines)
+   - Complete 3-column email UI with vanilla JavaScript
+   - All CRUD operations, keyboard shortcuts, bulk actions
+   - Responsive design with mobile fallbacks
+
+2. **`app/emails/frontend/views.py`** (23 lines)
+   - FastAPI router serving email template
+   - `/emails` endpoint returns HTMLResponse
+
+3. **`main.py`** (modified)
+   - Added `emails_views` import
+   - Registered email frontend router
+
+4. **`app/shared/frontend/base.html`** (modified)
+   - Added "Email" navigation link in top navbar
+
+### State Management
+
+JavaScript maintains:
+- `emails` - Array of email objects from API
+- `currentEmailId` - Currently selected email
+- `currentFilter` - Active classification filter ('all', 'invoice', etc.)
+- `selectedEmails` - Set of email IDs for bulk operations
+- `searchTimeout` - Debounce timer for search input
+- `autoRefreshInterval` - 30-second polling timer
+
+### API Calls
+
+- `GET /api/v1/emails?limit=100&classification={filter}&q={query}` - Load emails
+- `GET /api/v1/emails/{id}` - Load email detail
+- `PUT /api/v1/emails/{id}` - Update email (mark read, archive)
+- `PUT /api/v1/emails/{id}/classify` - Update classification
+- `POST /api/v1/emails/{id}/reprocess` - Reclassify with AI
+- `DELETE /api/v1/emails/{id}` - Soft delete
+- `POST /api/v1/emails/process` - Manual fetch new emails
+- `GET /api/v1/emails/stats/summary` - Load statistics
+- `GET /api/v1/email-rules` - Load email rules
+
+### Responsive Behavior
+
+- **Desktop (>1200px)**: Full 3-column layout
+- **Tablet (768-1200px)**: Narrower sidebars (280px, 260px)
+- **Mobile (<768px)**: Stacked layout, analysis sidebar hidden, smaller filter pills
+
+## Next Steps (Future Enhancements)
+
+1. **Attachment Preview**: Inline image preview, PDF viewer
+2. **Real-time Updates**: WebSocket for instant new email notifications
+3. **Advanced Search**: Full-text search with filters (date range, sender, has:attachment)
+4. **Email Compose**: Send replies or create new emails
+5. **Email Rules UI**: Full CRUD interface in modal (partially implemented)
+6. **Threading**: Group emails by conversation thread
+7. **Labels/Tags**: Custom user-defined labels beyond classification
+8. **Export**: Bulk export emails to CSV/JSON
+9. **Performance**: Virtual scrolling for 1000+ emails
+
