Fix ollama not reachable from host due to hardcoded OLLAMA_HOST in entrypoint

The IPEX-LLM bundled start-ollama.sh hardcodes OLLAMA_HOST=127.0.0.1 and
OLLAMA_KEEP_ALIVE=10m, overriding docker-compose environment variables and
preventing external connections through Docker port mapping.

- Add custom start-ollama.sh that honours env vars with sensible defaults
- Mount it read-only into the container
- Fix LD_LIBRARY_PATH env var syntax (: -> =)
- Add .gitignore for IDE/swap/webui data files
- Update CHANGELOG and README with fix documentation
