Fix timezone configuration and Ollama dependencies

- Fix mem0 library hardcoded US/Pacific timezone in Docker build
- Add TZ=Europe/Prague environment variable to containers
- Add missing ollama Python library to requirements.txt
- Add Ollama environment variables to MCP container
- Include test scripts for Ollama configuration validation

This resolves timestamp issues where memories were created with
incorrect Pacific timezone (-07:00) instead of local time (+02:00).
