feat: 门诊手术中计费功能

- 数据库：在adm_charge_item表添加SourceBillNo字段
- 后端实体类：更新ChargeItem.java添加SourceBillNo字段
- 前端组件：创建手术计费界面（基于门诊划价界面）
- 后端API：扩展PrePrePaymentDto支持手术计费标识
- 后端Service：扩展getChargeItems方法支持手术计费过滤
- 门诊手术安排界面：添加【计费】按钮

注意事项：
- 需要手动执行SQL脚本：openhis-server-new/sql/add_source_bill_no_to_adm_charge_item.sql
- 术后一站式结算功能待后续开发

+# Java Spring Boot Patterns
+
+## Design Patterns
+
+### Pattern 1: Input Validation
+
+Always validate input before processing:
+
+```python
+def validate_input(data):
+    if data is None:
+        raise ValueError("Data cannot be None")
+    if not isinstance(data, dict):
+        raise TypeError("Data must be a dictionary")
+    return True
+```
+
+### Pattern 2: Error Handling
+
+Use consistent error handling:
+
+```python
+try:
+    result = risky_operation()
+except SpecificError as e:
+    logger.error(f"Operation failed: {e}")
+    handle_error(e)
+except Exception as e:
+    logger.exception("Unexpected error")
+    raise
+```
+
+### Pattern 3: Configuration Loading
+
+Load and validate configuration:
+
+```python
+import yaml
+
+def load_config(config_path):
+    with open(config_path) as f:
+        config = yaml.safe_load(f)
+    validate_config(config)
+    return config
+```
+
+## Anti-Patterns to Avoid
+
+### ❌ Don't: Swallow Exceptions
+
+```python
+# BAD
+try:
+    do_something()
+except:
+    pass
+```
+
+### ✅ Do: Handle Explicitly
+
+```python
+# GOOD
+try:
+    do_something()
+except SpecificError as e:
+    logger.warning(f"Expected error: {e}")
+    return default_value
+```
+
+## Category-Specific Patterns: General
+
+### Recommended Approach
+
+1. Start with the simplest implementation
+2. Add complexity only when needed
+3. Test each addition
+4. Document decisions
+
+### Common Integration Points
+
+- Configuration: `assets/config.yaml`
+- Validation: `scripts/validate.py`
+- Documentation: `references/GUIDE.md`
