- Added ContactCompanyLink model for linking contacts to companies with primary role handling.
- Implemented endpoint to link contacts to companies, including conflict resolution for existing links.
- Updated auth service to support additional password hashing schemes.
- Improved sag creation and update processes with new fields and validation for status.
- Enhanced UI for user and group management, including modals for group assignment and permissions.
- Introduced new product catalog and improved sales item structure for better billing and aggregation.
- Added recursive aggregation logic for financial calculations in cases.

+# Sales and Aggregation Implementation Plan
+
+## 1. Data Model Proposals
+
+### 1.1 `sag_salgsvarer` Improvements
+We will enhance the existing `sag_salgsvarer` table to support full billing requirements, margin calculation, and product linking.
+
+**Current Fields:**
+- `id`, `sag_id`, `type` (sale), `description`, `quantity`, `unit`, `unit_price`, `amount`, `currency`, `status`, `line_date`
+
+**Proposed Additions:**
+| Field | Type | Description |
+|-------|------|-------------|
+| `product_id` | INT (FK) | Link to new `products` catalog (nullable) |
+| `cost_price` | DECIMAL | For calculating Gross Profit (DB) per line |
+| `discount_percent` | DECIMAL | Discount given on standard price |
+| `vat_rate` | DECIMAL | Default 25.00 for DK |
+| `supplier_id` | INT (FK) | Reference to `vendors` table (if exists) or string |
+| `billing_method` | VARCHAR | `invoice`, `prepaid`, `internal` (matches `tmodule_times`) |
+| `is_subscription` | BOOLEAN | If true, pushes to subscription system instead of one-off invoice |
+
+### 1.2 New `products` Table
+A central catalog for standard items (Hardware, Licenses, Fees) to speed up entry and standardize reporting.
+
+```sql
+CREATE TABLE products (
+    id SERIAL PRIMARY KEY,
+    sku VARCHAR(50) UNIQUE,
+    name VARCHAR(255) NOT NULL,
+    description TEXT,
+    category VARCHAR(50),       -- 'hardware', 'license', 'consulting'
+    cost_price DECIMAL(10,2),
+    sales_price DECIMAL(10,2),  -- Suggested RRP
+    unit VARCHAR(20) DEFAULT 'stk',
+    supplier_id INTEGER,
+    is_active BOOLEAN DEFAULT TRUE,
+    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
+);
+```
+
+### 1.3 Aggregation Rules
+The system will distinguish between **Direct** costs/revenue (on the case itself) and **Aggregated** (from sub-cases).
+
+- **Direct Revenue** = (Sum of `sag_salgsvarer.amount`) + (Sum of `tmodule_times` where `billable=true` * `hourly_rate`)
+- **Total Revenue** = Direct Revenue + Sum(Child Cases Total Revenue)
+
+## 2. UI Structure for "Varer" (Items) Tab
+
+The "Varer" tab on the Case Detail page will have a split entry/view design.
+
+### 2.1 Top Section: Quick Add
+A horizontal form to quickly add lines:
+- **Product Lookup**: Searchable dropdown.
+- **Manual Override**: Description field auto-filled but editable.
+- **Numbers**: Qty, Unit, Price.
+- **Result**: Total Price auto-calculated.
+- **Action**: "Add Line" button.
+
+### 2.2 Main List: Combined Billing View
+A unified table showing everything billable on this case:
+
+| Type | Date | Description | Qty | Price | Disc | Total | Status | Actions |
+|------|------|-------------|-----|-------|------|-------|--------|---------|
+| 🕒 Time | 02-02 | Konsulentbistand | 2.5 | 1200 | 0% | 3000 | `Approved` | [Edit Time] |
+| 📦 Item | 02-02 | Ubiquiti Switch | 1 | 2500 | 10% | 2250 | `Draft` | [Edit] [Del] |
+| 🔄 Sub | -- | *Sub-case: Installation i Aarhus* | -- | -- | -- | 5400 | `Calculated` | [Go to Case] |
+
+### 2.3 Summary Footer (Sticky)
+- **Materials**: Total of Items.
+- **Labor**: Total of Time.
+- **Sub-cases**: Total of Children.
+- **Grand Total**: Ex VAT and Inc VAT.
+- **Margin**: (Sales - Cost) / Sales %.
+- **Action**: "Create Invoice Proposal" button.
+
+## 3. Aggregation Logic (Recursive)
+
+We will implement a `SalesAggregator` service that traverses the case tree.
+
+**Algorithm:**
+1. **Inputs**: `case_id`.
+2. **Fetch Direct Items**: Query `sag_salgsvarer` for this case.
+3. **Fetch Direct Time**: Query `tmodule_times` for this case. Calculate value using `hourly_rate`.
+4. **Fetch Children**: Query `sag_relationer` (or `sag_sager` parent_id) to find children.
+5. **Recursion**: For each child, recursively call `get_case_totals(child_id)`.
+6. **Summation**: Return object with `own_total` and `sub_total`.
+
+**Python Service Method:**
+```python
+def get_case_financials(case_id: int) -> CaseFinancials:
+    # 1. Own items
+    items = db.query(SagSalgsvarer).filter(sag_id=case_id).all()
+    item_total = sum(i.amount for i in items)
+    item_cost = sum(i.cost_price * i.quantity for i in items)
+
+    # 2. Own time
+    times = db.query(TmoduleTimes).filter(case_id=case_id, billable=True).all()
+    time_total = sum(t.original_hours * get_hourly_rate(case_id) for t in times)
+
+    # 3. Children
+    children = db.query(SagRelationer).filter(kilde_sag_id=case_id).all()
+    child_total = 0
+    child_cost = 0
+
+    for child in children:
+        child_fin = get_case_financials(child.malsag_id)
+        child_total += child_fin.total_revenue
+        child_cost += child_fin.total_cost
+
+    return CaseFinancials(
+        revenue=item_total + time_total + child_total,
+        cost=item_cost + child_cost,
+        # ... breakdown fields
+    )
+```
+
+## 4. Preparation for Billing (Status Flow)
+
+We define a strict lifecycle for items to prevent double-billing.
+
+### 4.1 Status Lifecycle for Items (`sag_salgsvarer`)
+1.  **`draft`**: Default. Editable. Included in Preliminary Total.
+2.  **`approved`**: Locked by Project Manager. Ready for Finance.
+    - *Action*: Lock for Billing.
+    - *Effect*: Rows become read-only.
+3.  **`billed`**: Processed by Finance (exported to e-conomic).
+    - *Action*: Integration Job runs.
+    - *Effect*: Linked to `invoice_id` (new column).
+
+### 4.2 Billing Triggers
+- **Partial Billing**: Checkbox select specific `approved` lines -> Create Invoice Draft.
+- **Full Billing**: Bill All Approved -> Generates invoice for all `approved` items and time.
+- **Aggregation Billing**:
+  - The invoicing engine must accept a `case_structure` to decide if it prints one line per sub-case or expands all lines. Default to **One line per sub-case** for cleanliness.
+
+### 4.3 Validation
+- Ensure all Approved items have a valid `cost_price` (warn if 0).
+- Ensure Time Registrations are `approved` before they can be billed.
