Reorganize notebook setup and update agent-memory-server to 0.12.3

- Collect all environment setup under 'Environment Setup' header in 01_what_is_context_engineering.ipynb
- Convert memory example from markdown to executable Python cell
- Fix MemoryManager references to use correct MemoryClient API
- Update docker-compose to use agent-memory-server:0.12.3 instead of :latest
- Tested locally: services start successfully and health check passes
