Fix integration tests after merge - correct ClientSession API usage and tool names

- Fix ClientSession callback registration to use constructor parameters instead of request_context.session
- Update tool names to match actual example servers:
  - long_running_task (not slow_operation) for progress testing
  - generate_poem (not analyze_sentiment) for sampling testing
  - book_table (not book_restaurant) for elicitation testing
  - process_data (not send_notification) for notifications testing
- Fix completion test to test prompts instead of non-existent tools
- All integration tests now pass (16/16)
