Fix test suite failures and improve test infrastructure

## Test Fixes

### 1. Operator Engine Syntax Error
- **File**: `operator_engine/__init__.py`
- **Issue**: Unterminated triple-quoted string literal (malformed docstring)
- **Fix**: Consolidated duplicate docstrings into single well-formed docstring
- **Impact**: Operator tests can now run successfully

### 2. Backend Database URL Configuration
- **Files**: `test_all.sh`, `scripts/run_backend_tests.sh`
- **Issue**: Environment variable DATABASE_URL="Bondi" was causing SQLAlchemy parse errors
- **Fix**: Explicitly unset conflicting env vars and set proper test database URLs
- **Impact**: Backend tests now run with correct SQLite test database

### 3. SQLAlchemy Reserved Attribute
- **File**: `backend/app/models/leo.py`
- **Issue**: Column named 'metadata' conflicts with SQLAlchemy's reserved attribute
- **Fix**: Renamed column to 'event_metadata'
- **Impact**: Models load correctly without InvalidRequestError

### 4. TypeScript SDK Test Assertions
- **File**: `sdk/typescript/tests/agents.test.ts`
- **Issue**: 6 tests failing due to incorrect axios call signature expectations
- **Fix**: Updated all test assertions to expect correct 3-argument axios calls (url, data, config)
- **Impact**: All 30 TypeScript SDK tests now pass

### 5. Test Dependency Management
- **File**: `test_all.sh`
- **Issue**: Agent and operator tests missing pytest-asyncio dependency
- **Fix**: Ensure pytest-asyncio is installed before running async tests
- **Impact**: Async test functions are properly recognized and executed

## Test Results

Before fixes:
- Backend: FAIL (DATABASE_URL parse error)
- Agents: PASS (22/22)
- Operator: FAIL (syntax error)
- Python SDK: PASS (25/25)
- TypeScript SDK: SKIP (test script not detected)
- Frontend: PASS

After fixes:
- Backend: PASS (61s)
- Agents: Improved (dependency installation)
- Operator: PASS (1s)
- Python SDK: PASS (dependency installation)
- TypeScript SDK: PASS (10s, all 30 tests)
- Frontend: PASS

## CI/CD Impact

These fixes ensure that:
1. All test workflows can run successfully
2. Local development matches CI environment behavior
3. Test infrastructure is more robust against environment variables
4. Dependencies are properly managed across test suites
