fix: add missing session parameters to controller method calls

- Add db_session parameter to all RoomController.add() and update() calls in test_room_ics_api.py
- Fix TranscriptController.upsert_topic() calls to include session parameter in conftest.py fixture
- Fix TranscriptController.upsert_participant() and delete_participant() calls to include session parameter in API views
- Remove invalid setup_database fixture references, use pytest-async-sqlalchemy's database fixture instead
- Update CalendarEventController.upsert() calls to include session parameter

These changes ensure all controller methods receive the required session parameter
as part of the SQLAlchemy 2.0 migration pattern where sessions are explicitly managed.

+# AsyncIO Event Loop Analysis for test_attendee_parsing_bug.py
+
+## Problem Summary
+The test passes but encounters an error during teardown where asyncpg tries to use a different/closed event loop, resulting in:
+- `RuntimeError: Task got Future attached to a different loop`
+- `RuntimeError: Event loop is closed`
+
+## Root Cause Analysis
+
+### 1. Multiple Event Loop Creation Points
+
+The test environment creates event loops at different scopes:
+
+1. **Session-scoped loop** (conftest.py:27-34):
+   - Created once per test session
+   - Used by session-scoped fixtures
+   - Closed after all tests complete
+
+2. **Function-scoped loop** (pytest-asyncio default):
+   - Created for each async test function
+   - This is the loop that runs the actual test
+   - Closed immediately after test completes
+
+3. **AsyncPG internal loop**:
+   - AsyncPG connections store a reference to the loop they were created with
+   - Used for connection lifecycle management
+
+### 2. Event Loop Lifecycle Mismatch
+
+The issue occurs because:
+
+1. **Session fixture creates database connection** on session-scoped loop
+2. **Test runs** on function-scoped loop (different from session loop)
+3. **During teardown**, the session fixture tries to rollback/close using the original session loop
+4. **AsyncPG connection** still references the function-scoped loop which is now closed
+5. **Conflict**: SQLAlchemy tries to use session loop, but asyncpg Future is attached to the closed function loop
+
+### 3. Configuration Issues
+
+Current pytest configuration:
+- `asyncio_mode = "auto"` in pyproject.toml
+- `asyncio_default_fixture_loop_scope=session` (shown in test output)
+- `asyncio_default_test_loop_scope=function` (shown in test output)
+
+This mismatch between fixture loop scope (session) and test loop scope (function) causes the problem.
+
+## Solutions
+
+### Option 1: Align Loop Scopes (Recommended)
+Change pytest-asyncio configuration to use consistent loop scopes:
+
+```python
+# pyproject.toml
+[tool.pytest.ini_options]
+asyncio_mode = "auto"
+asyncio_default_fixture_loop_scope = "function"  # Change from session to function
+```
+
+### Option 2: Use Function-Scoped Database Fixture
+Change the `session` fixture scope from session to function:
+
+```python
+@pytest_asyncio.fixture  # Remove scope="session"
+async def session(setup_database):
+    # ... existing code ...
+```
+
+### Option 3: Explicit Loop Management
+Ensure all async operations use the same loop:
+
+```python
+@pytest_asyncio.fixture
+async def session(setup_database, event_loop):
+    # Force using the current event loop
+    engine = create_async_engine(
+        settings.DATABASE_URL,
+        echo=False,
+        poolclass=NullPool,
+        connect_args={"loop": event_loop}  # Pass explicit loop
+    )
+    # ... rest of fixture ...
+```
+
+### Option 4: Upgrade pytest-asyncio
+The current version (1.1.0) has known issues with loop management. Consider upgrading to the latest version which has better loop scope handling.
+
+## Immediate Workaround
+
+For the test to run cleanly without the teardown error, you can:
+
+1. Add explicit cleanup in the test:
+```python
+@pytest.mark.asyncio
+async def test_attendee_parsing_bug(session):
+    # ... existing test code ...
+
+    # Explicit cleanup before fixture teardown
+    await session.commit()  # or await session.close()
+```
+
+2. Or suppress the teardown error (not recommended for production):
+```python
+@pytest.fixture
+async def session(setup_database):
+    # ... existing setup ...
+    try:
+        yield session
+        await session.rollback()
+    except RuntimeError as e:
+        if "Event loop is closed" not in str(e):
+            raise
+    finally:
+        await session.close()
+```
+
+## Recommendation
+
+The cleanest solution is to align the loop scopes by setting both fixture and test loop scopes to "function" scope. This ensures each test gets its own clean event loop and avoids cross-contamination between tests.
